Abstract

An implantable atrial defibrillator and method provides cardioverting electrical energy to the atria of a human heart in need of cardioversion. The atrial defibrillator includes a first detector for detecting R
waves of the heart, a second detector for detecting T waves of the heart, and a third detector for detecting atrial activity of the heart. An atrial fibrillation detector is responsive to the third detector for determining when the atria of the heart are in need of cardioversion. A
cardioverting stage applies the cardioverting electrical energy to the atria of the heart when the atria of the heart are in need of cardioversion, after the second detector detects a T wave, and in timed relation to an R
wave detected by the first detector after the detected T
wave is completed. The atrial defibrillator includes a timer for timing a predetermined delay time after the T
wave is detected, which delay time must be completed before the atria are cardioverted in timed relation to a detected R wave to assure that the detected T wave is completed.
