Figure 1 A: Cross-section of a Riata dual-coil high-voltage implantable cardioverter-defibrillator lead. The redundant cables are coated in ethylene tetrafluoroethylene, which are shown in blue, and the central coil pace-sense conductor with stylet lumen is encased in a tube of polytetrafluoroethylene, shown in green. B: Cross-section of a Quattro Secure model 6947 dual-coil high-voltage implantable cardioverter-defibrillator lead. This lead has one ethylene tetrafluoroethylene–coated cable per lumen and the pace-sense coil, which is encased in a tube of polytetrafluoroethylene, is offset from the center of the lead.
