Abstract:
A method for providing resynchronization therapy to a heart, comprising:(a) determining whether to allow the heart to proceed at a natural pulse rate; (b) if it is determined at step (a) that the heart should proceed at a natural pulse rate, then sensing a natural depolarization event with a first electrode in a right atrium, not stimulating the left atrium without monitoring for a depolarization within the left atrium, but subsequently stimulating one or more ventricular walls with at least a second electrode during a cardiac cycle; and (c) if it is determined at step (a) that the heart should not proceed at a natural pulse rate, then stimulating a left atrium with a third electrode without monitoring for a (depolarization within the left atrium and subsequently stimulating one or more ventricular walls with at least the second electrode during a cardiac cycle.
