ABSTRACT:
There is provided a pacing system, preferably a VDD system having a single pass lead with one or two ventricular electrodes and a pair of atrial electrodes. The pacemaker has timing and logic capability for determining when an atrial back-up pulse, such an atrial synchronization pulse, can be delivered, and also whether the pacemaker can provide for continuing atrial pacing. The pacemaker is provided with a plurality of modules for determining the likelihood that a delivered atrial pace pulse resulted in atrial contraction, and for storing data relating to the probable capture or no.sub.-- capture result of each delivered pace pulse. One of the capture-determining modules is a timing module which stores a plurality of rules by which a sequence of events and rates surrounding a delivered atrial pace pulse is analyzed to determine the probability of capture. The pacemaker carries out capture probability determinations following each delivered pace pulse, and on the basis of such continuous determinations evaluates atrial pace pulse capture efficiency, and adjusts the atrial pace pulse output level to optimize atrial pacing.
