Abstract
A pacemaker includes apparatus and method for testing the integrity of an insulated pacemaker lead to detect lead degradation at an early stage and warn the user. An electronic switch is placed between two ends of an insulated pacemaker lead that couples a pacemaker housing to the heart of a pacemaker user. The pacemaker electronics circuit asserts a control signal to the switch, opening the switch and interrupting the continuity of the insulated pacemaker lead. After the switch interrupts continuity of the lead, an onboard lead integrity tester tests for insulation leakage of the insulated pacemaker leads by measuring a quality factor, Q, of the insulated lead.
