Patent ID: 7941219

Claim:
A method, implementable in a pacemaker, for detecting capture, comprising: determining an intersite sensing interval based on an intersite pacing delay and an intersite conduction delay associated with first and second pacing sites; delivering pacing pulses to the first pacing site and the second pacing site, the pacing pulses separated in time by the intersite pacing delay; timing the intersite sensing interval; during the intersite sensing interval, sensing at the first pacing site for a depolarization propagated to the first pacing site from the second pacing site; and detecting capture of the first pacing site and the second pacing site if the depolarization propagated from the second pacing site is not sensed, wherein determining the intersite sensing interval, delivering the pacing pulses, timing the intersite sensing interval, and detecting capture are performed by the pacemaker.
