Abstract
An implantable cardiac device returns activations of corresponding right and left chambers of a heart to inter-chamber synchrony. A sensing circuit senses intracardiac signals representing right and left chamber ventricular electrical activity. A detector determines if a predetermined characteristic of the electrogram signals indicates dissociation of the corresponding right and left chambers. If dissociation is indicated, a pulse generator stimulates at least one of the corresponding chambers to restore inter-chamber synchrony.
