Abstract
There is disclosed an improved pacer for controlling tachycardia. Following each tachycardia confirmation, a burst of a programmed number (e.g., 15) of stimulating pulses is generated. The rates of the bursts increase from cycle to cycle; thus following each tachycardia confirmation, a pulse burst at a different rate is generated. The rate of a burst which is successful in terminating tachycardia is stored, and following the next tachycardia confirmation the stored rate is used for the first burst which is generated. In this manner, there is a greater likelihood that tachycardia will be terminated following the first burst since a previously successful rate is used. Only if success is not achieved does scanning of the burst rate ensue, starting with the previously successful rate.
