Patent ID: 8280509

Claim:
A cardiac capture verification system, comprising: sensing circuitry configured to sense cardiac response signals resulting from pacing pulses associated with a plurality of capture verification modes; capture detection circuitry coupled to the sensing circuitry and configured to analyze the cardiac response signals to detect capture in accordance with the plurality of capture verification modes, at least one capture verification mode of the plurality of capture verification modes having a temporal relationship between delivery of a pacing pulse and detection of capture of heart tissue by the pacing pulse that is different from another capture verification mode of the plurality of capture verification modes; and a processor coupled to the capture detection circuitry and configured to evaluate the plurality of capture verification modes, the processor configured to select one or more capture verification modes based on the evaluation of the plurality of capture verification modes and based on a time interval duration of each of the one or more capture verification modes, the time interval duration measured between a given pacing pulse and a cardiac signal feature used for capture detection for such pacing pulse, the processor configured to implement capture verification using the selected one or more capture verification modes.
