<p>An implantable atrial defibrillator (30) delays therapy intervention for a delay time period after initial detection of fibrillation to provide the atria with an opportunity to spontaneously revert to normal sinus rhythm before cardioversion is attempted. A timer (76) times the delay time period responsive to the first initial detection of fibrillation by a fibrillation detector (70). After timer time-out, the fibrillation detector redetects for atrial fibrillation. If the atria are still in fibrillation, a cardiovertor (77) cardioverts the atria. If the atria are not in fibrillation, cardioverting therapy is withheld.</p> |
