Premature ventricular contraction trigeminy are extra, abnormal heartbeats that originate in the Purkinje fibers of the ventricles. The PVC occurs with every third 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.
