Classification: A61N

Abstract:
An implantable stimulation device comprising:a ventricular arrhythmia detector; an atrial pacer that is operative to generate atrial pacing pulses for delivery to an atrium of the heart; a generator that generates one of a cardioversion and defibrillation waveform for delivery to the heart; a controller connected to the detector, pacer, and generator, wherein the controller is operative in response to detection of a ventricular arrhythmia by the ventricular arrhythmia detector to control the atrial pacer to generate the atrial pacing pulses, and wherein the controller is further operative to control the generator to generate the waveform in timed relation to a delivered atrial pacing pulse; and a synchronizer that synchronizes the application of electrical energy to the heart with a delivered atrial pacing pulse.
