Abstract
In general, the disclosure describes techniques for detecting lead related conditions, such as lead fractures or other lead integrity issues. As described herein, delivering an electrical signal through selected electrodes may result in, reveal, or amplify noise if a lead related condition is present. A processor may detect electrical noise indicative of the lead related condition subsequent to the delivery of the electrical signal, and identify a lead related condition in response to detecting the noise.

A method comprising:
- delivering an electrical signal between two or more implanted electrodes and via an implanted medical lead that carries at least one of the two or more implanted electrodes;
- sensing an electrogram signal with the two or more implanted electrodes and via the implanted medical lead during a period having a predetermined length subsequent to delivery of the electrical signal;
