Premature ventricular complexes (PVCs) are common in the general population, usuallyasymptomatic, and deemed to be benign in structurally normal hearts. The spectrum of "benign" outflow tract PVCs ranges from single PVCs to recurrent non-sustained ventricular tachycardia (NSVT). Short-coupled right...
