An implantable cardiac stimulation device and method optimizesnpacing effectiveness of a patient's heart. A pulse generator delivers rightnand left pacing pulses to corresponding right and left chambers of thenheart with a selected pacing delay between the right pacing pulse and thenleft pacing pulse wherein the selected pacing delay is within a continuumnfrom left chamber pacing only, to simultaneous right and left chambernpacing, and to right chamber pacing only. A sensor senses a parameter,nsuch as ventricular pressure, associated with pacing effectiveness. Ancontrol circuit selects the pacing delay, which maximizes the sensednparameter. |
