Abstract
An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in response to detection of an atrial fibrillation episode and stores selected data associated with the detected atrial fibrillation episode. The atrial defibrillator includes a cardiovertor which provides successive applications of cardioverting electrical energy to the atria of the heart until one of the pulses successfully cardioverts the atria. A memory system stores selected heart activity data in connection with the detected episode including heart activity data related to initial detection of the atrial fibrillation episode and heart activity data occurring from before and until after the application of the cardioverting electrical energy which successfully cardioverts the atria of the heart.
