Abstract
The invention relates to a method and apparatus for diagnosis of conductor anomalies, such as insulation failures, in an implantable medical device, such as an implantable cardioverter defibrillator (ICD), a pacemaker, or a neurostimulator. Insulation failures are detected and localized by identifying changes in electrical fields via surface (skin) potentials. Small variations in potential are detected along the course of the electrode near the site of insulation failure.
