Abstract:
An implantable atrial defibrillator for use in a system for the defibrillation of the atria of a patient's heart by a pair of atrial defibrillation electrodes, said defibrillator comprising:an implantable housing;an atrial fibrillation detector contained within said housing;a pulse generator contained within said housing and operatively associated with said atrial fibrillation detector;said pulse generator configured for delivering a first atraial defibrillation pulse across said first pair of atrial defibrillation electrodes upon the detection of atrial fibrillation; andsaid pulse generator configured for delivering a second atrial defibrillation pulse across said pair of atrial defibrillation electrodes after said first defibrillation pulse; wherein said second atrial defibrillation pulse follows said first atrial defibrillation pulse by 0 to 500 milliseconds.
