ABSTRACT:
An implantable cardioverter/defibrillator/pacemaker (ICD) device having tiered level therapies, detects an arrhythmia through an electrode adapted to be coupled to a patient's heart. An output capacitor is coupled to the electrode through an output switch. A charging circuit, coupled to the output capacitor, charges the output capacitor to a programmed energy level. A control circuit, coupled to the charging circuit and the output switch, generates control signals to control the charging of the output capacitor and the closure of the output switch in accordance with a prescribed tiered therapy. The control circuit dynamically adjusts the rate zone boundaries, prior to a subsequent arrhythmia redetection, to include all lower rate zones into a current rate zone; and, in the event that the last programmed shock of the current rate zone has been delivered, the control circuit also dynamically readjusts the rate zone boundaries, prior to a subsequent arrhythmia redetection, to include the current rate zone in a higher rate zone.
