Abstract
An apparatus and method for verifying capture by a selected pacing electrode in a multi-site pacemaker. A switching circuit switches the input of an evoked response sensing channel to an unselected electrode. A pacing pulse is then output by the selected electrode, and the presence or absence of capture is determined from the output of the evoked response sensing channel. In one embodiment, a backup pacing pulse is output by an unselected electrode if a loss of capture is detected.
