METHODS AND SYSTEMS FOR DETECTING ATRIAL CONTRACTION TIMING FIDUCIALS WITHIN A SEARCH WINDOW FROM A VENTRICULARLY IMPLANTED LEADLESS CARDIAC PACEMAKER

摘要

A ventricularly implantable medical device that includes a sensing module that is configured to identify a search window of time within a cardiac cycle to search for an atrial artifact. Control circuitry in the ventricular implantable medical device is configured to deliver a ventricular pacing therapy to a patient's heart, wherein the ventricular pacing therapy is time dependent, at least in part, on an atrial event identified in the search window of time.
