Abstract
An arrhythmia control method and device are disclosed which monitor the cardiac state of a patient, utilize an arrhythmia recognition algorithm to detect and distinguish among bradycardia, sinus rhythm, supraventricular tachycardia and ventricular fibrillation, and deliver therapy in the form of electrical energy to cardiac tissue to revert selected arrhythmias and restore normal sinus rhythm. In its preferred form the device is an implantable combined dual chamber pacing and cardioverting device that is adapted to be electrically connected to the atrium and ventricle for sensing the atrial and ventricular waveforms and deliverying shock therapy thereto as required. The arrhythmia recognition algorithm utilizes the sensed atrial and ventricular waveform data for, among other things, distinguishing between ventricular tachycardia and supraventricular tachycardia.
