Abstract
An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion and thereafter gradually returns the cardiac rate of the heart to a normal cardiac rate. The atrial defibrillator includes a first detector for detecting atrial activity of the heart, and an atrial fibrillation detector, responsive to said first detector, for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a cardioverter responsive to the atrial fibrillation detector for applying the cardioverting electrical energy to the atria of the heart when the atria are in need of cardioversion, and a pacing output for pacing the ventricles of the heart at a decreasing cardiac rate from a base rate to a final rate lower than the base rate after the atria of the heart are successfully cardioverted.
