Abstract
A method and apparatus for discriminating among the various normal and pathologic tachycardias. In response to the detection of tachycardia, far-field ventricular electrograms sensed using atrial electrodes and far-field atrial electrograms sensed using ventricular electrodes are analyzed in order to categorize the source and type of tachyarrhythmia detected. The detection method and apparatus may be employed in conjunction with dual chamber anti-bradycardia pacemakers to avoid pacemaker mediated tachycardias or may be employed to mediate the delivery of pacing energy or cardioversion/defibrillation shock energy to a malfunctioning heart, in the context of an implantable antitachycardia device.
