Abstract:
An implantable cardiac stimulation device which optimizes pacing effectiveness of a patient's heart comprising:a pulse generator configured to: deliver right and left pacing pulses to corresponding respective right and left chambers of the heart with a selected pacing delay between the delivery of the right pacing pulse and the delivery of the left pacing pulse within a continuum from left chamber pacing alone, to the delayed pacing between right chamber and left chamber, to simultaneous right chamber and left chamber pacing, and to right chamber pacing alone; a sensor that senses a parameter associated with pacing effectiveness; and a control circuit that selects the pacing delay which maximizes the sensed parameter, wherein the control circuit includes a processor programmed to cause the pulse generator to deliver the right and left pacing pulses with varying pacing delays until a maximum of the parameter is sensed by the sensor.
