Abstract
In an implantable medical device a real-time left atrial pressure (“LAP”) signal obtained from a patient's heart is used as a feedback control mechanism to adjust one or more device parameters. In one example the device identifies specific characteristics and attributes of the LAP signal that correlate to hemodynamic performance, and adjusts the device parameters to optimize the LAP characteristics and attributes. In a dual-chamber pacing system, the controlled operating parameter may include the atrioventricular pacing delay, and LAP attribute suitable for controlling the atrioventricular pacing delay time intervals of v-wave, a-wave, and/or c-wave characteristics of the LAP signal.
