ABSTRACT:
In a system that includes a ventricular pacemaker, the system adjusts an atrioventricular delay to synchronize the onset of isovolumetric contraction with the completion of ventricular filling. The system adjusts the atrioventricular delay as a function of electrical and pressure data from the heart. The system further adjusts the atrioventricular delay as a function of measurements of the time interval between a cardiac occurrence such as a ventricular pace and the completion of ventricular filling. The system may also adjust the atrioventricular delay as a function of the heart rate.
