An implantable atrial defibrillator provides cardioverting electrical energy to the atria of a human heart in need of cardioversion. The atrial defibrillator includes a first detector for detecting ventricular activations of the heart, a second detector for detecting atrial activity of the heart, and an atrial fibrillation detector responsive to the second detector for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a cardioverter for applying the cardioverting electrical energy to the atria of the heart when the atria of the heart are in need of cardioversion, and a timer delay stage responsive to the first detector for causing the cardioverter to apply the cardioverting electrical energy to the atria of the heart a predetermined delay time after the first detector detects one of the ventricular activations and before the T wave of the heart immediately following the one of the ventricular activations.

A post-surgical cardioverting system and method applies cardioverting electrical energy to the atria of the heart of a post-surgical heart patient. The system includes a first lead including a first elongated electrode having a proximal end and a distal end, a second lead including a second elongated electrode having a proximal end and a distal end, and sutures for releasably anchoring the distal ends of the first and second electrodes to the pericardium and disposing the first and second electrodes along the pericardium overlying the right and left atria respectively. A non-implantable cardiovertor is coupled to the first and second leads for applying the cardioverting electrical energy to the first and second electrodes. When cardioversion is no longer required, the first and second leads may be pulled out of the patient's chest.

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.

An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion. The atrial defibrillator includes a first detector for sensing atrial activity of the heart, an atrial fibrillation detector responsive to the first detector for determining when the atria of the heart are in need of cardioversion and a second detector for detecting ventricular activations of the heart. The atrial defibrillator further includes a cardioverter for applying cardioverting electrical energy to the atria of the heart when the atria of the heart are in need of cardioversion and is responsive to the second detector for applying the cardioverting electrical energy to the atria of the heart in predetermined time relation to a detected ventricular activation. The detection of atrial activity of the heart is interrupted when a ventricular activation of the heart is detected by the second detector.

An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion and thereafter paces the heart in a demand mode. The atrial defibrillator includes a first detector for detecting atrial activity of the heart, an atrial fibrillation detector responsive to the atrial activity detected by the first detector for determining when the atria of the heart are in need of cardioversion, and a cardiovertor 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. The defibrillator further includes a pacer for pacing the heart in a demand mode, a depletable power source for providing electrical power to the first detector, the atrial fibrillation detector, the cardiovertor, and the pacer, and an enable/disable stage for enabling the pacer in response to the cardiovertor applying the cardioverting electrical energy to the atria and thereafter disabling the pacer in response to the occurrence of a predetermined event for conserving the depletable power source.

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.

The atrial defibrillator includes a first detector for detecting atrial activity of the heart and an atrial fibrillation detector responsive to the first detector for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a pacing output circuit responsive to the atrial fibrillation detector for pacing the ventricles of the heart at a pacing rate when the atria of the heart are in need of cardioversion and a cardioverter stage for applying the cardioverting electrical energy to the atria of the heart after the pacing output circuit has paced the ventricles for a predetermined number of cardiac cycles. The pacing output circuit stabilizes the cardiac rate of the heart prior to the application of the cardioverting electrical energy.
