  • Method of automatic evoked response sensing vector selection using evoked response waveform analysis
    Patent number: 7123963
    Abstract: A cardiac pacing device and method for automatically selecting an optimal evoked response sensing vector based on an evaluation of the evoked response signal quality are provided. Electrode switching circuitry allows selection of multiple sensing electrode vectors. Capture detection circuitry provides capture and loss of capture signal characteristics determined during a pacing threshold search to be used in determining evoked response signal quality parameters. An optimal evoked response sensing vector is selected based on evoked response signal quality parameters meeting predetermined criteria for reliable evoked response sensing.
    Type: Grant
