摘要:
An apparatus comprises a cardiac signal sensing circuit configured for coupling electrically to a plurality of electrodes and to sense intrinsic cardiac activation at three or more locations within a subject's body using the electrodes; a stimulus circuit configured for coupling to the plurality of electrodes; a signal processing circuit electrically coupled to the cardiac signal sensing circuit and configured to determine a baseline intrinsic activation vector according to the sensed intrinsic cardiac activation; and a control circuit electrically coupled to the cardiac signal sensing circuit and stimulus circuit and configured to: initiate delivery of electrical pacing therapy using initial pacing parameters determined according to the baseline intrinsic activation vector; initiate sensing of a paced activation vector; and adjust one or more pacing therapy parameters according to the paced activation vector.
