ABSTRACT:
An antitachyarrhythmia device employing a tachycardia termination methodology in which antitachycardia pacing and cardioversion pulse therapies are combined. After detection of an arrhythmia which would normally result in delivery of a cardioversion or defibrillation pulse, the device begins to charge high voltage output capacitors. During the charging period, the device deliveries an antitachycardia pacing pulse regimen, in an attempt to terminate the arrhythmia prior to delivery of the cardioversion or defibrillation pulse. Following delivery of the antitachycardia pacing pulse regimen, the device evaluates the heart rhythm to determine whether the tachyarrhythmia has terminated. If so, delivery of a high voltage cardioversion or defibrillation pulse is aborted. If the tachyarrhythmia has not terminated, the high voltage pulse is delivered.
