Patent abstract
A pulse is delivered to the atrium using an electrode configuration that includes at least a pulse cathode electrode. Cardiac activity in the atrium is sensed using a unipolar electrode configuration to provide a sensed signal wherein the unipolar electrode configuration does not include the pulse cathode electrode. A determination as to whether the pulse caused an atrial evoked response is made based on a maximum derivative value of the sensed signal with respect to time, a comparison of the sensed signal to a parameter or an integral of the sensed signal with respect to time.
