Abstract
A pacemaker which is provided with an improved automatic regulation circuit which is capable of distinguishing between a fusion beat and loss of capture. The failure to sense an evoked potential following a stimulus may be due to either. The cause is determined by generating a high-energy back-up pulse shortly after the stimulus. Failure to capture by the back-up pulse is an indication that there was just a fusion beat; the sensing of an evoked potential is an indication that the stimulus failed to capture.
