ABSTRACT:
An implantable cardiac stimulation device provides selective atrial pacing upon detection of a premature ventricular complex (PVC). The device comprises a premature ventricular complex detector that detects premature complexes of the heart, and a sensing circuit that senses atrial events. The device further comprises a P wave discriminator that identifies an atrial event sensed by the sensing circuit following detection of a premature ventricular complex as one of a retrograde P wave and a normal sinus P wave, and an atrial pulse generator that delivers an atrial pacing pulse responsive to the discriminator identifying an atrial event sensed by the sensing circuit following detection of a premature ventricular complex as a retrograde P wave.
