Premature Ventricular Contractions

Premature ventricular contractions (PVCs), also known as ventricular premature beats, are premature ventricular activations originating from ectopic pacemaker sites below the atrioventricular node. A PVC following every sinus P wave is called bigeminy; a PVC occurring after every two sinus P waves is called trigeminy; two consecutive PVCs are called a couplet; three or more consecutive PVCs are called ventricular tachycardia. A PVC occurring between two normal sinus beats is called an interpolated PVC. PVCs are also classified as unifocal or multifocal according to their morphology and coupling interval relative to the sinus QRS complex.
