<P> 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 fibers in the ventricles rather than by the sinoatrial node , the normal heartbeat initiator . The electrical events of the heart detected by the electrocardiogram ( ECG ) allow a PVC to be easily distinguished from a normal heart beat . Although a PVC can be a sign of decreased oxygenation to the heart muscle , often PVCs are benign and may even be found in otherwise healthy hearts . </P>
