Are heart PVCs serious?
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 you live a long life with frequent PVCs? In general even those with fairly frequent PVC's who have had underlying heart disease ruled out can be reassured and likely have a good prognosis.
