Premature Ventricular Contractions. Description. Premature ventricular contractions (PVCs) are beats which are initiated in the ventricles or lower chambers of the heart, prematurely. As opposed to PACs, when the SA node (the natural pacemaker of the heart) gets interrupted, PVCs do not interrupt the SA node.
Premature ventricular contractions (PVCs) are heartbeats that occur earlier than they should. These early beats briefly interrupt the heart 's rhythm. A PVC may feel like a skipped heartbeat or a flutter. PVCs are the most common type of change in heart rhythm. They are common in children and teens as well as in adults.
