How often is it OK to have PVCs?

Can a PVC cause sudden death? – PVCs can increase your risk of sudden cardiac death, especially if they occur frequently. According to one study, experiencing more than 12 PVCs daily increases your risk of sudden cardiac death. However, they don’t lead to sudden cardiac death in most people.

Why am I getting so many PVCs?

Etiology – In the vast majority of cases, PVCs have no known cause and occur spontaneously. Common known etiologies include excess caffeine consumption, excess catecholamines, high levels of anxiety, and electrolyte abnormalities. Specific electrolyte changes found in those who experience PVCs are low blood potassium, low blood magnesium, and high blood calcium.

• Alcohol, tobacco, and illicit drugs are also associated with PVCs as are stimulant-based medications.
• Patients suffering from sleep deprivation also experience PVCs.
• There are numerous cardiac and non-cardiac pathologies that are causative of PVCs.
• Examples include cardiomyopathy, mitral valve prolapse, and myocardial infarction.

Any structural heart disease that alters conduction pathways due to tissue alterations can cause PVCs. Non-cardiac examples are hyperthyroidism, anemia, and even hypertension. Patient populations with higher risks of cardiovascular disease and clinically poor cardiovascular markers have a higher occurrence of PVCs.

Is it normal to feel PVCs everyday?

Occasional PVCs are commonly experienced by people of all ages. The age groups most frequently associated with PVCs are in their 20s, 30s and sometimes 40s. These are typically associated with lifestyle-related causes. If you regularly start to notice the occurrence of PVCs, it can be alarming.

How many PVCs are considered high?

For patients with underlying structural heart disease, it is important to reduce the PVC burden if it is high (ie, >15 percent or 15,000 PVCs/day ) in order to lower the risk of developing PVC-induced cardiomyopathy. The first-line therapy for these patients is to reduce PVC burden with beta blockers.

Can frequent PVCs damage your heart?

Typical heartbeat – In a typical heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal. The signal then travels through the atria to the atrioventricular (AV) node and into the ventricles, causing them to contract and pump blood.

• PVCs are irregular contractions that start in the ventricles instead of the atria.
• The contractions usually beat sooner than the next expected heartbeat.
• The cause of premature ventricular contractions isn’t always clear.
• Certain things including heart diseases or changes in the body can make cells in the lower heart chambers electrically unstable.

Heart disease or scarring may cause the heart’s signals to be misrouted. Premature ventricular contractions may be caused by:

Certain medications, including decongestants and antihistamines Alcohol or drug misuse Stimulants such as caffeine or tobacco Increased levels of adrenaline in the body due to exercise or anxiety Injury to the heart muscle due to disease

Certain lifestyle choices and health conditions may make a person more likely to develop premature ventricular contractions (PVCs). Risk factors for PVCs include:

Caffeine Tobacco Alcohol Stimulants such as cocaine or methamphetamines Exercise — if you have certain types of PVCs Anxiety Heart attack Heart disease, including congenital heart disease, coronary artery disease, heart failure and a weakened heart muscle (cardiomyopathy)

Having frequent premature ventricular contractions (PVCs) or certain patterns of them might increase the risk of developing irregular heart rhythms (arrhythmias) or weakening of the heart muscle (cardiomyopathy). Rarely, when accompanied by heart disease, frequent premature contractions can lead to chaotic, dangerous heart rhythms and possibly sudden cardiac death.

Is it safe to exercise with PVCs?

When you start an exercise program, you want to make sure your heart is healthy. If you’re one of the many people who experience premature ventricular contractions (PVCs) during and after exercise, you may wonder whether it’s safe for you to exercise with PVCs.

This article breaks down everything you need to know about the safety of exercising with PVCs. If you have PVCs, this info will kick-start your journey toward minimizing the risk and maximizing the rewards of regular exercise. Note that you should always consult a healthcare professional before beginning any exercise program.

PVCs are a type of abnormal heartbeat that originates in the ventricles, disrupting the regular rhythm and causing the sensation of either a skipped beat or palpitations. They are common and usually harmless, and many people who experience them have no symptoms ( 1 ).

Your heart is made up of two atria and two ventricles. Typically, the signal for your heartbeat starts in the right atrium in the sinoatrial node and travels to both the left and right ventricles, allowing your heart to coordinate its rhythm in your heartbeat. But during a PVC, the opposite happens, and the contraction starts prematurely in the Purkinje network of the ventricles ( 2 ).

When this happens, you may not experience any symptoms, or you might notice the irregular rhythm. The irregularity commonly creates a sensation that your heart has skipped a beat or jumped in your chest, followed by a sensation of fluttering in your chest ( 1 ).

• If the contraction is strong enough, it may leave you feeling lightheaded or anxious and possibly cause some chest discomfort.
• Still, most PVCs feel like heart palpitations and are benign, meaning they do not need treatment.
• Most people will experience them at some point in their lives ( 1 ).
• However, if the PVCs are prolonged or frequent, if you get dizzy or lose consciousness, or if you have any underlying heart disease risks, you should consult a healthcare professional.

In these cases, PVCs can be serious. Summary PVCs are common and cause an abnormal heartbeat. They are typically benign but may be more dangerous for those with underlying heart conditions. In most cases, there is no known cause of PVCs. Researchers have suggested that too much caffeine, high anxiety, or irregularities in electrolyte balance could affect PVCs, with lower levels of magnesium or potassium and high levels of calcium in the body being of particular importance ( 1 ).

Getting too little sleep, drinking alcohol, and using stimulants or other substances can further worsen PVCs. Likewise, hypoxia (not enough oxygen in the blood), exercise, and certain medications can induce PVCs ( 3 ). If you’re having symptoms of PVCs, it’s a good idea to check your overall stress levels.

By reducing stress, you may be able to reduce the frequency of PVCs ( 1 ). Summary The causes of PVCs are not well understood, but anxiety, caffeine, and electrolyte imbalances are thought to be key factors. Occasional PVCs are very common. Researchers who have monitored subjects for 24–48 hours have found that 50–75% of the study population had PVCs.

They have also found that the prevalence of PVCs is higher in males and increases with age, although even young children experience them ( 3, 4 ). Research suggests that PVCs occur more frequently in those who smoke, are taller, are Black, get minimal exercise, have heart disease, or have higher blood pressure ( 5 ).

Summary Occasional PVCs are very common, even in people who have healthy hearts. However, some factors, such as older age and smoking, are associated with a greater frequency of PVCs. PVCs are usually considered benign unless they are frequent, but it can be difficult to decipher what classifies as “frequent.” Some research classifies frequent PVCs as occurring in more than 20% of your heartbeats in 24 hours ( 6 ).

A healthy heart beats 86,000–144,000 times in 24 hours, so 20% of that is well over 17,000 irregular heartbeats in 24 hours ( 7 ). Other research takes a different approach to frequent PVCs by counting how many occur in 1 hour. In this case, 30 or more PVCs per hour is considered frequent ( 1 ). Still other research suggests a simpler way to assess your risk factor: If PVCs occur more than 12 times per day, you should seek the advice of a medical professional.

Some studies have found that 12 or more PVCs per day predict a greater chance of long-term heart problems ( 8 ). Summary If you experience PVCs more than 30 times per hour or more than 12 times per day, you should see a doctor. The short answer: It depends on how frequently you experience PVCs and whether the irregular contractions decrease or increase after exercise.

In some cases, exercise can decrease the frequency of PVCs. In other cases, it can induce PVCs — these are called EI-PVCs (exercise-induced premature ventricular contractions) ( 9 ). If you are healthy, do not have heart disease, and experience occasional PVCs that do not worsen with physical activity, exercising should not present any danger.

If your PVCs are exercise-induced, they may still be harmless, but it’s important to note when they happen. Research suggests that if EI-PVCs are common during the recovery phase of your workouts, you may be at much greater risk of cardiovascular disease and mortality than if the PVCs occur only during the workout ( 1, 10 ).

If you experience frequent PVCs, it’s a good idea to consult a healthcare professional before performing heavy exercise. There are two reasons for this. First, frequent PVCs can indicate underlying heart disease or lead to conditions such as cardiomyopathy ( 11 ). In the case of cardiomyopathy, research has found that the best way to prevent worsening disease is to halt intense exercise ( 12 ).

Secondly, if your PVCs are a result of low electrolyte balance, as mentioned earlier, intense exercise will only deplete electrolytes more ( 13 ). Potassium is further depleted through sweat, and magnesium levels drop after exercise because magnesium is a necessary metabolic component that helps with muscle recovery and energy utilization ( 13, 14, 15, 16, 17 ).

• If low electrolytes are causing your PVCs, you may find that supplementation helps decrease the frequency of these irregular contractions.
• But it’s best to consult a medical professional before beginning a supplement routine ( 18 ).
• Research on this treatment method is still ongoing ( 19 ).
• As always, make sure to check with a doctor if you’re having repeated PVCs and are worried about the associated risks.

Summary Exercising with PVCs is generally considered safe, but if you have frequent PVCs that become worse during or after exercise, it’s worth getting a medical opinion. Research suggests that EI-PVCs happen 7% of the time in healthy people and up to 54% of the time in those with cardiovascular disease ( 9 ).

While PVCs are not uncommon during exercise, the impact of exercise on the frequency of PVCs is the most important factor to note. If you experience more frequent PVCs during or after exercise, further investigation is warranted to ensure there are no further cardiac concerns. If your PVCs are suppressed with exercise and do not increase during the recovery period, it’s likely your PVCs are benign ( 20 ).

Furthermore, while exercise may temporarily increase PVCs, some research suggests it’s a good treatment for arrhythmia in the long term ( 21 ). In a 2015 study, researchers monitored 5,011 athletes without cardiac abnormalities during exercise using electrocardiography ( 22 ).

1. Of those, 331 athletes showed a reduction of arrhythmia after 3–12 months of repeated exercise and 83 of those 331 completely stopped having the abnormal heart effects ( 22 ).
2. Likewise, in children and teenagers with no underlying cardiac disease, exercise has proven to be a good method of suppressing PVCs ( 4, 22 ).

Summary It’s important to note how exercise affects your PVC symptoms. If PVCs increase or worsen after exercise, it’s a good idea to seek out more tests. However, in some cases, exercise will suppress PVCs or decrease their frequency long-term. No single type of exercise has been found to be best for people with PVCs.

• Much of the research on PVCs and exercise uses aerobic exercise as the parameter.
• With that in mind, low intensity forms of cardiovascular exercise, such as hiking, walking, and biking, are most likely the best because they will strengthen your heart — provided they aren’t worsening your symptoms.
• A strength training routine is also a good idea to balance out your program.

If you notice that higher intensity exercise — or any exercise, for that matter — increases the frequency of your PVCs, it’s a good idea to consider backing off or choosing other modalities such as yoga, Pilates, or weight training while you consult a healthcare professional.

• Summary Aerobic exercise is the most studied form of exercise in people with PVCs.
• A weight training routine is also worth including for comprehensive fitness.
• While experts do not fully understand the causes of PVCs, stress and lifestyle factors are likely related to how frequently they occur.
• If you’re concerned about the frequency of your PVCs, check with a healthcare professional for next steps.

With stress testing and heart rate monitoring, they should be able to give you a path forward. Exercising is generally safe if you only occasionally experience PVCs and they don’t worsen during or after your workouts. In fact, aerobic exercise may help reduce your symptoms in the long term.

Do PVCs ever go away?

Prevention and Treatment – Tell your doctor of any symptoms of PVCs so you can determine if there is an underlying cause that needs to be treated, such as other rhythm problems, serious heart problems, anxiety, anemia or infections. You should also report any symptoms such as dizziness or fainting.

In those with healthy hearts, occasional PVCs are harmless and usually resolve on their own without treatment. Some PVC symptoms can be managed through lifestyle changes — limiting caffeine, tobacco and alcohol and stress, for example. Treatment for patients who experience PVCs on a regular basis includes medication such as beta blockers and calcium blockers.

For patients whose symptoms are severe, a catheter ablation may be recommended. During catheter ablation, an electrophysiologist uses radiofrequency energy to cauterize the area of the heart where the PVCs originate. In patients with heart problems such as heart failure or heart disease, PVCs may be a sign of a more dangerous heart rhythm to come.

Why won t my PVCs go away?

One factor that is sometimes out of our control is stress. Stress can be a big contributor to PVCs and will hopefully be something we can all reduce. It is impossible to eliminate, no matter how hard we try. Do everything you can to reduce stress or manage stress.

Is it bad to have multiple PVCs in a row?

What are premature ventricular contractions (PVCs)? – Premature ventricular contractions (PVCs) are a type of abnormal heartbeat. Your heart has 4 chambers: 2 upper atria and 2 lower ventricles. Normally, a special group of cells start the signal for your heartbeat.

These cells are in the sinoatrial (SA) node in the right atrium. The signal quickly moves down your heart’s conducting system. It travels to the left and right ventricle. As it travels, the signal triggers nearby parts of your heart to contract. This allows your heart to squeeze in a coordinated way. With a PVC, the signal to start your heartbeat comes from one of the ventricles instead.

This signal is premature, meaning it happens before the SA node has had a chance to fire. The signal spreads through the rest of your heart and can cause a heartbeat that is different than normal. Depending on when the premature beat happens, you may feel nothing at all, a skipped heartbeat, lightheaded, short of breath, or even chest pain.

PVCs that happen only once in a while are common in people of all ages, but they’re more common in older people. PVCs can happen in people without any heart disease, but they’re more common in people with some kind of heart disease. PVCs rarely cause problems unless they occur again and again over a long period of time.

In such cases, they can lead to a PVC-induced cardiomyopathy, or a weakening of the heart muscle from too many PVCs. Most often, this can go away once the PVCs are treated.

Why do I get PVCs after eating?

Palpitations make you feel like your heart is beating too hard or too fast, skipping a beat, or fluttering. You may notice heart palpitations in your chest, throat, or neck. They can be bothersome or frightening. They usually aren’t serious or harmful, though, and often go away on their own.

Shortness of breath Dizziness Chest pain Fainting

After your doctor takes your medical history and looks you over, they may order tests to find the cause. If they find one, the right treatment can reduce or get rid of the palpitations. If there’s no underlying cause, lifestyle changes can help, including stress management,

Strong emotions like anxiety, fear, or stress, They often happen during panic attacks,Vigorous physical activity Caffeine, nicotine, alcohol, or illegal drugs such as cocaine and amphetamines Medical conditions, including thyroid disease, a low blood sugar level, anemia, low blood pressure, fever, and dehydration Hormonal changes during menstruation, pregnancy, or just before menopause. Sometimes, palpitations during pregnancy are signs of anemia, Medications, including diet pills, decongestants, asthma inhalers, and some drugs used to prevent arrhythmias (a serious heart rhythm problem) or treat an underactive thyroid Some herbal and nutritional supplements Abnormal electrolyte levels

Some people have palpitations after heavy meals rich in carbohydrates, sugar, or fat. Sometimes, eating foods with a lot of monosodium glutamate (MSG), nitrates, or sodium can bring them on, too. If you have heart palpitations after eating certain foods, it could be due to food sensitivity.

Prior heart attack Coronary artery disease Heart failure Heart valve problemsHeart muscle problems

Your doctor will:

Give you a physical exam Take down your medical historyWant to know about your current medications, diet, and lifestyleAsk for specifics about when, how often, and under what circumstances your palpitations occur

Sometimes, a blood test can help your doctor find the cause of your palpitations. Other useful tests include: Electrocardiogram ( EKG ) : This can be done while you’re at rest or exercising, The latter is called a stress EKG, In both cases, the test records your heart’s electrical signals and can find unusual heart rhythms.

1. Holter monitoring : You’ll wear a monitor on your chest.
2. It continuously records your heart’s electrical signals for 24 to 48 hours.
3. It can identify rhythm differences that weren’t picked up during an EKG.
4. Event recording : You’ll wear a device on your chest and use a handheld gadget to record your heart’s electrical signals when symptoms occur.

Chest X-ray: Your doctor will check for changes in your lungs that could come from heart problems. For example, if they find fluid in your lungs, it may come from heart failure. Echocardiogram : This is an ultrasound of your heart. It provides detailed information about its structure and function.

1. If necessary, your doctor may refer you to a cardiologist for more tests or treatment.
2. This depends on their cause.
3. Often, palpitations are harmless and go away on their own.
4. In that case, no treatment is needed.
5. If your doctor doesn’t find a cause, they may advise you to avoid the things that might trigger the palpitations.

Strategies may include: Ease anxiety and stress, Leave a stressful situation and try to be calm. Anxiety, stress, fear, or panic can cause palpitations. Other common ways to stay calm include:

Relaxation exercises Yoga Tai chi Biofeedback Guided imagery Aromatherapy

Cut out certain foods, beverages, and other substances. These may include:

AlcoholNicotine Caffeine Illegal drugs

Avoid medications that act as stimulants, You may have to steer clear of:

Cough and cold medicinesCertain herbal and nutritional supplements

If lifestyle changes don’t help, you may be prescribed medications. In some cases, these will be beta-blockers or calcium -channel blockers. If your doctor finds a reason for your palpitations, they will focus on treating that reason. If they’re caused by a medication, your doctor will try to find a different treatment.

If they represent an arrhythmia, you may get medications or procedures. You may also be referred to a heart rhythm specialist known as an electrophysiologist. Make sure to check in with your doctor. Often, palpitations aren’t serious, but they can be related to abnormal heart valves, heart rhythm problems, or panic attacks,

Always call a doctor if palpitations change in nature or increase suddenly. Call 911 right away if you have these symptoms along with palpitations:

Dizziness ConfusionLightheadednessPassing outShortness of breathPain, pressure, or tightness in the chest, neck, jaw, arms, or upper back

How many PVCs are normal in 48 hours?

If you record a person’s heartbeat for 48 hours on an electrocardiogram (ECG), about 75 percent of people will have at least one PVC. PVCs usually come as a single PVC. Two PVCs in succession is called a doublet PVC.

What is a normal PVC burden?

Most studies have reported that a PVC burden of at least 10% is associated with cardiomyopathy, and reduction to 10% PVCs should initially receive medical therapy to suppress PVCs.

Can anxiety cause constant PVCs?

Stress and anxiety can trigger premature ventricular contractions (PVCs), a type of arrhythmia. Premature ventricular contractions (PVCs) can be caused by emotional stress and anxiety, among other factors. PVCs are a common type of arrhythmia (irregular heartbeat) that may cause you to feel like your heart is fluttering.

1. In a standard healthy population, PVCs have been observed in up to 75% of subjects on 48-hour cardiac monitoring.
2. Emotional stress, including feelings of anxiety and anger, can trigger PVCs and other arrhythmias.
3. PVCs don’t always require treatment — it’s possible to occasionally experience PVCs without it affecting your heart and health.

However, you might need treatment if you get frequent or bothersome PVCs, or if you have a heart condition. Yes. Stress and anxiety can increase your risk of experiencing PVCs. Mental stress can trigger arrhythmias of all kinds, according to a 2022 study,

• A 2012 study looked at 1,144 Chinese patients with PVCs.
• It found that about one-third of the participants had symptoms of anxiety.
• Conversely, PVCs can cause anxiety and stress, especially if you experience them frequently.
• The feeling of a fluttering heartbeat, as well as worry about the state of your heart, can be anxiety-inducing.

Not everybody who experiences immense stress and anxiety will have an arrhythmia. A 2016 paper points out that some people are more susceptible to stress-related PVCs than others, although it’s not clear why this is.

Do PVCs make you tired?

PVCs 101 – Heart disease or scarring that interferes with the heart’s normal electrical impulses can cause PVCs. Certain medications, alcohol, stress, exercise, caffeine or low blood oxygen, which is caused by chronic obstructive pulmonary disease (COPD) or pneumonia, can also trigger them. Symptoms associated with PVCs include:

Fatigue Shortness of breath Dizziness or lightheadedness Very frequent PVCs

In individuals with these symptoms, PVCs are diagnosed through an electrocardiogram or a heart monitor worn by the patient. If you have normal heart function, PVCs are typically nothing to worry about. But for those with frequent PVCs or an underlying heart condition, such as congenital heart disease, PVCs can lead to cardiomyopathy (a weakened heart muscle) or a more severe type of arrhythmia.

Can a lot of PVCs make you tired?

What Are the Symptoms of PVCs? – Sometimes PVCs cause no symptoms at all. Other times, a patient may feel palpitations (irregular heartbeats). These can feel like “skipped” beats, or “flopping” in the chest. If PVCs are frequent, other symptoms can occur.

Why are PVCs worse at night?

What causes heart palpitations at night? – Usually, heart palpitations are harmless and don’t result from an underlying health problem. They happen when the heart beats out of rhythm or contracts (beats) too soon. Providers call this a premature ventricular contraction (PVC) or premature atrial contraction (PAC).

Anxiety, stress and depression, Heart palpitations are common during a panic attack, Dehydration and electrolyte imbalances. Electrolytes are minerals in the body. They control your heart’s rhythm. Drugs, including diet pills and nasal decongestants that contain pseudoephedrine. Nicotine can also cause heart palpitations. Extra weight and obesity, People who carry extra weight have a higher risk of abnormal heart rhythms and heart disease. Fever, Hormonal changes during menopause and changes that happen to the body during pregnancy. Heart palpitations during pregnancy are very common and usually harmless. Some food and drinks, including alcohol, caffeine and chocolate. Foods that are high in carbohydrates, sodium (salt), sugar or fat can lead to heart palpitations.

Less commonly, heart palpitations result from a health condition or disorder, including:

Anemia (low red blood cell count). Heart disease, including heart attack, heart failure or cardiomyopathy, Heart rhythm problems (arrhythmias) including atrial fibrillation (Afib), tachycardia (fast heart rate) and bradycardia (slow heart rate). Hypotension (low blood pressure) or hypoglycemia (low blood sugar ). Metabolic syndrome, Myocarditis, inflammation of the heart’s muscles that results from a viral infection. Thyroid problems, such as hyperthyroidism, Structural problems in the heart, including valve disease,

How many PVCs are considered high?

For patients with underlying structural heart disease, it is important to reduce the PVC burden if it is high (ie, >15 percent or 15,000 PVCs/day ) in order to lower the risk of developing PVC-induced cardiomyopathy. The first-line therapy for these patients is to reduce PVC burden with beta blockers.

What percentage of PVCs is too many?

WHEN TO TREAT IDIOPATHIC PVCs – In our practice we explain to patients that there are two primary indications for treating idiopathic PVCs: (1) to relieve symptoms or (2) in asymptomatic patients with presumed arrhythmia-induced cardiomyopathy, to try to reverse the cardiomyopathy by eliminating the PVCs.

• Some patients report severe symptoms due to their PVCs.
• Other patients appear to have no symptoms whatsoever, while still others are not overly bothered by the PVCs but are concerned that they may indicate they are at increased risk of cardiac events.
• In this last group, an evaluation such as outlined above that discloses no evidence of structural heart disease and reassurance by the physician may be all the treatment needed.

Even if they have no symptoms or only minimal symptoms, patients with a high PVC burden require follow-up because of the association between frequent PVCs and arrhythmia-induced cardiomyopathy.14, 15 What constitutes a “high” PVC burden remains a matter of debate.

Left ventricular dysfunction has generally been reported at PVC burdens above 15% to 25% of the total cardiac beats, though this percentage can be as low as 10%.14 Eliminating the high burden of PVCs in patients with left ventricular dysfunction may significantly improve left ventricular systolic function.15 It is likely, however, that more than PVC burden alone contributes to the development of the cardiomyopathy.14 Given these complexities, it is reasonable to request an electrophysiology consultation for patients who have more than rare PVCs.

What is rare? There is no defined standard, but a PVC burden less than 1% is reasonable. Treatment of the PVCs may be indicated in patients with systolic heart failure receiving cardiac resynchronization therapy, ie, a biventricular pacemaker. For cardiac resynchronization therapy to be clinically beneficial, close to 100% of heartbeats need to be paced, and frequent PVCs, even at a burden less than 10%, may undermine its effectiveness.16

Is it safe to exercise with PVCs?

When you start an exercise program, you want to make sure your heart is healthy. If you’re one of the many people who experience premature ventricular contractions (PVCs) during and after exercise, you may wonder whether it’s safe for you to exercise with PVCs.

In these cases, PVCs can be serious. Summary PVCs are common and cause an abnormal heartbeat. They are typically benign but may be more dangerous for those with underlying heart conditions. In most cases, there is no known cause of PVCs.

2. Research suggests that PVCs occur more frequently in those who smoke, are taller, are Black, get minimal exercise, have heart disease, or have higher blood pressure ( 5 ).

Summary Occasional PVCs are very common, even in people who have healthy hearts. However, some factors, such as older age and smoking, are associated with a greater frequency of PVCs. PVCs are usually considered benign unless they are frequent, but it can be difficult to decipher what classifies as “frequent.” Some research classifies frequent PVCs as occurring in more than 20% of your heartbeats in 24 hours ( 6 ).

1. A healthy heart beats 86,000–144,000 times in 24 hours, so 20% of that is well over 17,000 irregular heartbeats in 24 hours ( 7 ).
2. Other research takes a different approach to frequent PVCs by counting how many occur in 1 hour.
3. In this case, 30 or more PVCs per hour is considered frequent ( 1 ).
4. Still other research suggests a simpler way to assess your risk factor: If PVCs occur more than 12 times per day, you should seek the advice of a medical professional.

Some studies have found that 12 or more PVCs per day predict a greater chance of long-term heart problems ( 8 ). Summary If you experience PVCs more than 30 times per hour or more than 12 times per day, you should see a doctor. The short answer: It depends on how frequently you experience PVCs and whether the irregular contractions decrease or increase after exercise.

1. In some cases, exercise can decrease the frequency of PVCs.
2. In other cases, it can induce PVCs — these are called EI-PVCs (exercise-induced premature ventricular contractions) ( 9 ).
3. If you are healthy, do not have heart disease, and experience occasional PVCs that do not worsen with physical activity, exercising should not present any danger.

If your PVCs are exercise-induced, they may still be harmless, but it’s important to note when they happen. Research suggests that if EI-PVCs are common during the recovery phase of your workouts, you may be at much greater risk of cardiovascular disease and mortality than if the PVCs occur only during the workout ( 1, 10 ).

If you experience frequent PVCs, it’s a good idea to consult a healthcare professional before performing heavy exercise. There are two reasons for this. First, frequent PVCs can indicate underlying heart disease or lead to conditions such as cardiomyopathy ( 11 ). In the case of cardiomyopathy, research has found that the best way to prevent worsening disease is to halt intense exercise ( 12 ).

Secondly, if your PVCs are a result of low electrolyte balance, as mentioned earlier, intense exercise will only deplete electrolytes more ( 13 ). Potassium is further depleted through sweat, and magnesium levels drop after exercise because magnesium is a necessary metabolic component that helps with muscle recovery and energy utilization ( 13, 14, 15, 16, 17 ).

• If low electrolytes are causing your PVCs, you may find that supplementation helps decrease the frequency of these irregular contractions.
• But it’s best to consult a medical professional before beginning a supplement routine ( 18 ).
• Research on this treatment method is still ongoing ( 19 ).
• As always, make sure to check with a doctor if you’re having repeated PVCs and are worried about the associated risks.

Summary Exercising with PVCs is generally considered safe, but if you have frequent PVCs that become worse during or after exercise, it’s worth getting a medical opinion. Research suggests that EI-PVCs happen 7% of the time in healthy people and up to 54% of the time in those with cardiovascular disease ( 9 ).

1. While PVCs are not uncommon during exercise, the impact of exercise on the frequency of PVCs is the most important factor to note.
2. If you experience more frequent PVCs during or after exercise, further investigation is warranted to ensure there are no further cardiac concerns.
3. If your PVCs are suppressed with exercise and do not increase during the recovery period, it’s likely your PVCs are benign ( 20 ).

Furthermore, while exercise may temporarily increase PVCs, some research suggests it’s a good treatment for arrhythmia in the long term ( 21 ). In a 2015 study, researchers monitored 5,011 athletes without cardiac abnormalities during exercise using electrocardiography ( 22 ).

Of those, 331 athletes showed a reduction of arrhythmia after 3–12 months of repeated exercise and 83 of those 331 completely stopped having the abnormal heart effects ( 22 ). Likewise, in children and teenagers with no underlying cardiac disease, exercise has proven to be a good method of suppressing PVCs ( 4, 22 ).

Summary It’s important to note how exercise affects your PVC symptoms. If PVCs increase or worsen after exercise, it’s a good idea to seek out more tests. However, in some cases, exercise will suppress PVCs or decrease their frequency long-term. No single type of exercise has been found to be best for people with PVCs.

• Much of the research on PVCs and exercise uses aerobic exercise as the parameter.
• With that in mind, low intensity forms of cardiovascular exercise, such as hiking, walking, and biking, are most likely the best because they will strengthen your heart — provided they aren’t worsening your symptoms.
• A strength training routine is also a good idea to balance out your program.

If you notice that higher intensity exercise — or any exercise, for that matter — increases the frequency of your PVCs, it’s a good idea to consider backing off or choosing other modalities such as yoga, Pilates, or weight training while you consult a healthcare professional.

• Summary Aerobic exercise is the most studied form of exercise in people with PVCs.
• A weight training routine is also worth including for comprehensive fitness.
• While experts do not fully understand the causes of PVCs, stress and lifestyle factors are likely related to how frequently they occur.
• If you’re concerned about the frequency of your PVCs, check with a healthcare professional for next steps.

With stress testing and heart rate monitoring, they should be able to give you a path forward. Exercising is generally safe if you only occasionally experience PVCs and they don’t worsen during or after your workouts. In fact, aerobic exercise may help reduce your symptoms in the long term.
