Abstract

See full text

An intraoperative defibrillation test system for establishing defibrillation thresholds for an implantable cardioverter defibrillator (ICD) uses the actual ICD housing electrode, rather than a test housing electrode, as part of the test system. The intraoperative defibrillation test system includes the ICD, an external test station, and a test cable interconnecting the ICD with the test station. In one embodiment, the test cable is only connected to the ICD housing electrode and other test cables are used to connect to other implanted electrodes. In another embodiment, the test cable includes multiple conductors for connecting to all of the electrodes associated with the ICD, including the ICD housing electrode. In a further embodiment, the test cable includes a distal connector block that serves as a three-way T-between at least one port in a header of the ICD and an electrode lead.
