Abstract
The present invention relates, generally, to scientific and medical system methods for diagnosis of implantable cardioverter defibrillator (ICD) lead conductor anomalies, in particular conductor migration and externalization within an ICD implantable cardiac lead. The method uses an 'imaginary' component of the high frequency transmission line impedance having certain spectral changes that correspond to movements of the conductor or an 'imaginary impedance'. This allows the detection of conductor migration and small insulation failures.
