IMPLANTABLE MEDICAL SYSTEM WITH MEANS FOR DETERMINING WHETHER A LEAD-RELATED CONDITION EXISTS

摘要

An implantable medical system (26) with means (66) for analyzing characteristics of electrical signals generated on a lead by a test signal to determine whether a lead-related condition exists. The characteristics of the electrical signals induced on the lead by the test signal may be significantly different on a lead having an insulation breach or externalized conductor than on a lead not having such lead- related conditions. As such, the implantable medical device may be subject to a known test signal and analyze the signals on the lead to detect lead-related conditions.
