Abstract

An implantable medical device (IMD) (210) for managing therapy is provided that is couplable to a lead (220, 224) with an electrode (222, 232), a memory (294) configured to store program instructions and one or more processors (260). The one or more processors (260) 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) (412), determine a sensed right ventricle (RVs) event (414) by detecting a cardiac activity (CA) signal (402) reaches a threshold amplitude (410) and determine a maximum amplitude (420) in a determined period of time (418) after the CA signal (402) reaches the threshold amplitude (410), and determine an RAs,p-RVs interval (404) between the RAs,p event (412) and RVs event (414). The one or more processors (260) can also be configured to calculate an atrioventricular delay (AV) delay based on the RAs,p-RVs interval (404), and manage therapy, provided by the IMD (210), based on the AV delay that is calculated.
