Premature ventricular complexes (PVC) often represent increased ventricular automaticity or reentry phenonomen. The presence of PVCs may be benign but can indicate irritable ventricles. PVCs arrive earlier than expected and is usually wide (.12 seconds or more). Note that the T wave often points in an opposite direction from the QRS complex. A PVC every second complex is called ventricular bigeminy...every 3rd - ventricular trigeminy.
