When are pvcs worrisome?

When they: come in "runs" (repeated 3-4-5 in a row) or when they occur without 'coupling" (a stable amount of time) to a NORMAL beat!. Your PCP/Cardiologist will be able to determine this after a period of MONITORING! Hope this is helpful Dr Z

PVC's can be a: warning sign of other cardiovascular problems that need to be evaluated. They can also lead to the development of a cardiomyopathy when they are frequent (in general >15%). You need to be evaluated by a health care professional (preferably cardiologist or electrophysiologist) to determine your cause, potential risks and treatment options.
