ABSTRACT:
A combination lead for use with an implanted pulse generator which may be a pacemaker or defibrillator or combination thereof. The lead can deliver an electrical charge to pace, cardiovert or defibrillate the ventricles of the heart, and can sense cardiac activity in the heart. The lead includes atrial ring sensors capable of sensing electrical activity in the atrial cavity. The lead allows cardioversion and/or defibrillation stimuli to be provided by a large surface area electrode which is passively implanted in the ventricle, and allows the pulse generator to provide ventricular pacing appropriately synchronized to atrial depolarizations, cardioversion or defibrillation.
