ABSTRACT:
Cardiac pacing to treat ventricle dysynchrony for improved cardiac function is performed as follows. Early paced inter-ventricular asynchrony is determined during ventricular pacing. Baseline inter-ventricular asynchrony is determined without pacing. Average inter-ventricular asynchrony is calculated by averaging the early paced inter-ventricular asynchrony and the baseline inter-ventricular asynchrony. Atrio-ventricular delay and ventricular-ventricular delay are adjusted during ventricular pacing to yield the average inter-ventricular asynchrony for optimal intra-left ventricular resynchronization and maximal cardiac function. The elements above can be configured in software contained in an implantable medical device or embodied as a computer software product that includes a medium readable by a processor.
