Abstract
An implantable atrial defibrillator includes a lead system having a plurality of electrodes to deliver a cardioverting pulse to atria of a heart, for sensing A waves of the heart, and for sensing R waves of the heart. A first detector detects the A waves sensed by the lead system and a second detector detects the R waves sensed by the lead system. An inhibit stage defines an inhibit time period responsive to each detected R wave and an output provides the cardioverting pulse to the lead system responsive to an A wave being detected. The inhibit stage precludes provision of the cardioverting pulse during each inhibit time period.
