Premature ventricular contraction quadrigeminy are extra, abnormal heartbeats originating in the Purkinje fibers of the ventricles. The PVC occurs with every fourth heart beat. Patients may feel a PVC as a skipped beat or palpitation. Single beat premature ventricular contractions are very common and can often be asymptomatic in healthy patients.
