Abstract
A medical device system and method for detecting dislodgement of a lead determines one or more characteristics of a cardiac signal received via the lead that are associated with dislodgement of the lead during atrial fibrillation, and detects dislodgement of the ventricular lead based on the determined characteristics. The medical device and system provides a lead dislodgment alert in response to detecting dislodgement. In some examples, an implantable medical device withholds delivery of a defibrillation therapy based on detecting dislodgement of the lead.
