Abstract

An implantable atrial defibrillator for applying cardioverting electrical energy to the atria of a human heart.
The atrial defibrillator includes a first detector for sensing a depolarization activation wave at a first pair of locations of the heart and generating a first initiation signal and a second detector for sensing the depolarization activation wave between a second pair of locations of the heart and generating a second initiation signal. The atrial defibrillator also includes a timing circuit for timing the time between immediately successive depolarization activation waves of the heart in response to one of the first and the second initiation signals for commencing the timing. The atrial defibrillator also 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 timer times a time greater than a predetermined time interval.
