Patent ID: 7123963

Claim:
A method for automatically selecting evoked response sensing electrodes, comprising: selecting an evoked response sensing electrode pair; delivering a sequence of test pulses including a first set of test pulses having a first pulse energy exceeding a capture threshold and a second set of test pulses having a second pulse energy less than the capture threshold; setting a capture detection time window following each test pulse during which a signal is sensed using the selected evoked response sensing electrode pair; determining a maximum signal amplitude of the sensed signal occurring during the capture detection window following each of the test pulses included in the first set and the second set; determining a minimum value of the determined maximum signal amplitudes corresponding to the first set of test pulses; determining a signal quality parameter based on the minimum value of the maximum signal amplitudes corresponding to the first set of test pulses; and accepting the selected evoked response sensing electrode pair in response to the signal quality parameter.
