ABSTRACT:
An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart. The atrial defibrillator includes a first detector for sensing depolarization activation waves at a first area of the heart and producing a first signal, a second detector for sensing depolarization activation waves at a second area of the heart and producing a second signal, an analyzing circuit for determining if the first signal satisfies a first criterion and if the second signal satisfies a second criterion. The atrial defibrillator includes a third detector for sensing activity of the heart in at least one of the atria of the heart and an atrial fibrillation detector for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a cardioverting circuit for applying the cardioverting electrical energy to the atria of the heart when the atria of the heart are in need of cardioversion and when the first signal satisfies the first criterion and when the second signal satisfies the second criterion.
