ABSTRACT:
A system and method for verifying capture of the heart by one or more pacing pulses using an electrogram morphology-based technique. Capture is determined by comparing an evoked response electrogram recorded during a paced cycle with a template waveform representing a paced cycle in which capture is achieved. The comparison is facilitated and made more accurate by selecting a sensing vector in which an evoked response electrogram in which no capture occurs is most dissimilar to the template.
