Rhythm discrimination using information indicative of lead motion
First Claim
1. An apparatus including an implantable medical device, the implantable medical device (IMD) comprising:
- a receiver circuit, configured to be electrically coupled to an implantable lead, the receiver circuit configured to receive a response to an excitation signal applied to a conductor in the lead, the response modulated according to a change in an electrical characteristic of at least one conductor in the lead to provide information indicative of a movement of the implantable lead, the movement due at least in part to a motion of a heart;
an arrhythmia detection circuit configured to determine an arrhythmia status using the response information indicative of the movement of the implantable lead; and
an arrhythmia classification circuit, coupled to the arrhythmia detection circuit, the arrhythmia classification circuit configured to determine one or more of a location or a type of an arrhythmia, using the response information indicative of the movement of the implantable lead, in response to the arrhythmia detection circuit determining an arrhythmia status indicating that an arrhythmia is occurring or has occurred.

Abstract
Systems and methods for rhythm discrimination using the motion of an implantable lead are described. In an example, an implantable medical device can include a receiver circuit configured to be electrically coupled to 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 an arrhythmia detection circuit configured to determine an arrhythmia status using the information indicative of the movement of the implantable lead and an arrhythmia classification circuit configured to determine one or more of a location or a type of an arrhythmia, using the information indicative of the movement of the implantable lead, when the arrhythmia status indicates that an arrhythmia is occurring or has occurred.
