DETECTING LEAD RELATED CONDITION DURING DELIVERY OF THERAPEUTIC ELECTRICAL SIGNALS
First Claim
1. A method comprising:
- delivering a therapeutic electrical signal to a patient via an electrical path including at least one medical lead;
detecting a delivered energy and an impedance of the path during the delivery of the electrical signal; and
identifying a lead related condition when at least one of the detected delivered energy and the detected impendence traverses a respective threshold.

Abstract
In general, the disclosure describes techniques for detecting lead related conditions, such as lead fractures or other lead integrity issues. As described herein, lead related conditions are identified by detecting delivered energy and electrical path impedance during delivery of a therapeutic electrical to a patient. If one or both of the delivered energy and impedance traverse respective thresholds, a lead related condition may exist. The energy delivered during the electrical signal may be compared to the amount of energy the electrical signal was programmed to deliver to determine if the delivered energy is less than a threshold percentage of the programmed energy of the electrical signal. The impedance of the electrical path through which the therapeutic electrical signal is delivered may be compared to a threshold impedance value to determine if the impedance detected during the electrical signal is greater than the threshold.
