A premature ventricular contraction (PVC) also known as a premature ventricular complex ventricular premature contraction (or complex or complexes) (VPC) ventricular premature beat (VPB) or ventricular extrasystole (VES) is a relatively common event where the heartbeat is initiated by Purkinje fibres in the ventricles rather than by the sinoatrial node the normal heartbeat initiator.
