Ventricular bigeminy

Also calledventricular bigeminy PVC pattern · ventricular bigeminy

Definition

A repeating pattern in which each normal (usually sinus) beat is followed by a premature ventricular contraction, so that normal beats and PVCs alternate one to one. Each PVC has the usual PVC features, including a premature, abnormally shaped QRS that is usually wider than 120 ms.
