ABSTRACT:
An atrial cardiovertor/defibrillator provides therapy to the atria corresponding to the type of atrial arrhythmia occurring in the atria of the heart. The atrial cardiovertor/defibrillator includes a memory for storing respective different criteria for each of different types of atrial arrhythmia, a sensor for sensing activity of at least one of the atria of the heart to provide an electrogram signal, and a cardiovertor for providing a corresponding therapy to the heart for each of the different types of atrial arrhythmia. The cardiovertor/defibrillator further includes an atrial arrhythmia detector responsive to the electrogram signal and the stored criteria for identifying one of the types of atrial arrhythmia to cause the cardiovertor to provide therapy to the heart corresponding to the identified atrial arrhythmia.
