SYSTEMS AND METHODS FOR MANAGING ATRIAL-VENTRICULAR DELAY

Abstract: an implantable medical device (imd) for managing therapy is provided that can include a lead with an electrode, a memory configured to store program instructions and one or more processors. the one or more processors can be configured to execute the program instructions to determine a sensed right atrium (ras) event or a paced right atrial (rap) event (ras,p event), determine a sensed right ventricle (rvs) event by detecting a cardiac activity (ca) signal reaches a threshold amplitude and determining a maximum amplitude in a determined period of time after the ca signal reaches the threshold amplitude, and determine an ras,p-rvs interval between the ras,p event and rvs event. the one or more processors can also be configured to calculate an atrioventricular delay (av) delay based on the ras,p-rvs interval, and manage therapy, provided by the imd, based on the av delay that is calculated.
