Sensing window management of multipoint pacing
Abstract:
An apparatus for coupling to a plurality of electrodes implantable at a plurality of tissue sites of a heart chamber of a subject. The apparatus including a stimulus circuit configured to provide an electrical cardiac pacing stimulation to the plurality of electrodes, a switching circuit configured to select electrodes of the plurality of electrodes for electrical coupling to the stimulus circuit, and a control circuit including a heart rate sub-circuit configured to determine heart rate; and a pacing site activation sub-circuit configured to selectively change which electrodes of the plurality of electrodes are used to provide the electrical cardiac pacing stimulation therapy according to the determined heart rate.
