Ventricular premature complexes-c: ventricular premature complexes (vpcs) occur as a result of an ectopic foci that discharge anywhere in the myocardial wall of the ventricle. the impulse is conducted cell-to-cell through the myocardium at a slow rate, versus more quickly through the intended purkinje system, thereby producing an abnormally wide and bizarre qrs-t complex on ecg. vpcs are commonly seen with primary cardiac disease, secondary to trauma or systemic disease, or secondary to drug therapy. it is important to understand that they rarely cause any hemodynamic impairment unless they occur frequently, in which case they should be treated to prevent progression to more serious and potentially fatal arrhythmias such as ventricular tachycardia or ventricular fibrillation.
