Consider talking with a doctor about how you can exercise most safely. Because physical activity benefits your overall health, doctors won’t usually recommend stopping exercising just because you have PVCs. ![]() Intense and frequent exercisers may be at greater risk of having PVCs, but they don’t usually cause significant side effects. That’s according to a 2019 study that also found PACs to be associated with a higher risk of developing more severe arrhythmias, like atrial fibrillation or supraventricular tachycardia. While PVCs increase your risk of cardiomyopathy, PACs likely don’t. With PVCs, the bottom part of the heart (ventricle) contracts too early.īoth conditions can cause similar symptoms, especially a feeling of fluttering in the heart. Premature atrial contractions, or PACs, are when the top part of the heart (atrium) contracts before making a complete beat. What’s the difference between PVCs and PACs? The following are some frequently asked questions about PVCs. Having 10,000 PVCs a day means you have about a 10% PVC burden. To put those numbers in context, your heart beats about 100,000 times a day. Having thousands of PVCs a day can put you at risk for decreased heart function. How many times does your heart beat in a day? Talk with them about how to minimize your risks. If your doctor has already diagnosed heart disease, PVCs can increase your mortality risk or risk for early death. This can increase your risk of developing dilated cardiomyopathy, sometimes called an enlarged heart. Some studies say that having more than 1,000 PVCs a day can weaken your left ventricle over several years. It’s reversible in most patients if the PVCs are treated. Doctors refer to this as PVC-induced cardiomyopathy. This can make you feel faint and dizzy.Īccording to a 2017 report, having more than 10,000 and up to 20,000 PVCs a day can decrease your heart’s function. But if you have too many in a row, your heart may not pump enough blood, and your blood pressure will drop. Occasional PVCs are usually not problematic to you or your health. ![]() What are the potential complications of PVCs?
