Abstract
An implantable atrial defibrillator provides adaptive output voltage control. An atrial cardiovertor is responsive to an atrial fibrillation detector for applying a cardioverting voltage having a magnitude to the atria of a heart when the atria are in need of cardioversion. A memory stores data associated with each such voltage application. A computation stage computes from the stored data a percentage of success which is compared to lower and upper limits. The output voltage is incremented or decrement based upon the comparison. The output voltage may further be maintained within a fixed preselected voltage range.
