Abstract
Systems and methods for cardiac contraction detection using information indicative of lead motion are described. In an example, an implantable medical device can include a receiver circuit configured to be electrically coupled to conductor comprising a portion of an implantable lead and be configured to obtain information indicative of a movement of the implantable lead due at least in part to a motion of a heart. The device can include a processor circuit configured to determine whether a cardiac mechanical contraction occurred during a specified interval included in the obtained information indicative of the movement of the implantable lead. The processor circuit can be configured to determine information about the cardiac mechanical contraction using the obtained information indicative of the movement of the implantable lead.
