摘要
There is disclosed an implantable atrial defibrillator for applying cardioverting electrical energy to the atria of a heart when the atria are in need of cardioversion. The atrial defibrillator includes a sense channel adapted to be associated with at least one atrium of the heart to provide a cardiac signal during a plurality of cardiac cycles of the heart and a timer which determines a cardiac interval duration for each of the cardiac cycles. The defibrillator further includes an atrial detector for analyzing the cardiac signal provided by the sense channel during selected ones of the cardiac cycles wherein each one of the selected ones of the cardiac cycles has a cardiac interval greater than a predetermined duration.PPA cardioverter applies cardioverting electrical energy to the atria responsive to the atrial detector detecting atrial fibrillation of the heart.
