Abstract
Methods and systems for identifying dislodgement of an electrode, operably coupled to an implanted medical device, from fixation with the endocardium of a chamber of the heart of a patient can include obtaining a test electrogram, and measuring at least two parameters indicating a cavitary electrogram and taking an action, such as generating an electrode dislodgement alert and/or configuring the implanted medical device to disable therapy, when the cavitary electrogram is indicated. In embodiments, the two parameters include a test positive component magnitude and a test negative component magnitude. In embodiments, the test component magnitudes are compared to baseline component magnitudes determined from a baseline electrogram.
