Premature Ventricular Contractions (PVCs): A Narrative Review.

Premature ventricular complexes/contractions (PVCs) are relatively common, occurring in 3%-20% of the general population, and are often found during work-up of palpitations or incidentally on routine electrocardiographic testing. They are usually considered benign but can be a sign of underlying cardiac disease and cause significantly impairing symptoms. While often thought of as a problem for the cardiologist, it is not uncommon for PVCs to be identified initially in a primary care or inpatient general medicine setting. This paper will review etiologies, epidemiology, evaluation, and management of PVCs for the internist.
