Abstract
An active implantable medical device of the defibrillator/cardioverter type for the defibrillation or cardioversion of the atrium. The device is able to detect ventricular activity and to deliver conventional low energy ventricular stimulation pulses to the ventricle. It also delivers shock energy pulses having an energy level sufficient to achieve defibrillation and/or cardioversion. The atrial activity is detected to determine the moment at which the shock energy pulse can be delivered to the atrium. The device also recognizes when a ventricular depolarization occurs, and uses this event to control in a conditional manner the delivery of shock energy pulses. More particularly, shock energy pulses are delivered only when the detected ventricular activity indicates the occurrence of a ventricular depolarization following delivery of a ventricular stimulation pulse.
