Abstract
A dual chamber pacemaker is provided, preferably either DDDR or DDIR, having logic hardware and/or software for normally carrying out the DDIR or DDDR mode of operation, and further having means for carrying out a safe atrial pace method of operation in circumstances where normal atrial pacing could otherwise be competitive or result in loss of atrial capture. The pacemaker has means for detecting an atrial sense during PVARP, timing out a delay from the time of the early atrial sense, delivering a safe atrial pulse at the end of the delay, and controlling generation of a ventricular pace pulse in synchronous relation to the safe atrial pulse and with at least a minimum AV interval.
