Abstract
An implantable cardiac stimulation device and method optimizes pacing effectiveness of a patient's heart. A pulse generator delivers right and left pacing pulses to corresponding right and left chambers of the heart with a selected pacing delay between the right pacing pulse and the left pacing pulse wherein the selected pacing delay is within a continuum from left chamber pacing only, to simultaneous right and left chamber pacing, and to right chamber pacing only. A sensor senses a parameter, such as ventricular pressure, associated with pacing effectiveness. A control circuit selects the pacing delay, which maximizes the sensed parameter.
