ABSTRACT:
A pacing system provides for optimal hemodynamic cardiac function for parameters such as ventricular synchrony or contractility (peak left ventricle pressure change during systole or LV+dp/dt), or stroke volume (aortic pulse pressure) using system for calculating atrio-ventricular delays for optimal timing of a ventricular pacing pulse. The system deriving the proper timing using electrical or mechanical events having a predictable relationship with an optimal ventricular pacing timing signal. A look-up table relating the timing of such electrical or mechanical events to atrio-ventricular delay time intervals is provided for programming the pacing system.
