  • Rate controlled pacemaker system using AR interval for rate control
    Patent number: 5144950
    Abstract: A pacing system and method for delivering atrial stimulus pulses is provided, wherein detected AV interval is utilized for increasing or decreasing atrial pacing interval. The AV interval is compared with an AV reference value each cycle to determine direction of change of pacing, the AV reference being updated each cycle in accordance with a predetermined correlation of change of pacing interval and change of AV reference. The pacing system may be either DDDR or AAIR. In the AAIR embodiment, a single atrial lead is used and the far field ventricular R wave signal is sensed from the total electrocardiogram signal obtained from the atrial lead.
