摘要
An apparatus and method for tachyarrhythmia reversion uses multiple sensitivities programmed for automatic operation. A first (medium) sensitivity is used normally for the detection of sinus rhythm and ventricular tachycardia. A second (higher) sensitivity is designed for differentiating ventricular fibrillation from asystole. A third (lower) sensitivity can also be programmed into the device to differentiate between R-waves and high amplitude current of injury T- waves which may occur post shock. Following the delivery of antitachycardia therapy in the form of either antitachycardia pacing therapy or cardioversion shock therapy, there is a pause, or post therapy pacing delay for a period of time prior to the commencement of bradycardia support pacing. The magnitude of the delay period is substantially greater than the normal bradycardia support pacing standby interval.
