Premature ventricular contractions (PVCs, PVC) are premature heartbeats originating from the ventricles of the heart. Premature ventricular contractions are premature because they occur before the regular heartbeat.

Normal function of the heart

The heart has four chambers. The upper two chambers are the atria, and the lower two chambers are the ventricles.

The atria deliver blood to the ventricles, and the ventricles deliver blood to the lungs and to the rest of the body.

The right ventricle delivers blood to the lungs while the left ventricle delivers blood to the rest of the body.

The heartbeat (pulse) that we feel is caused by the contraction of the ventricles.
