Summary We report a case of Brugada syndrome with a high defibrillation threshold (DFT) in whom a subcutaneous array lead was used to lower the DFT in combination with a transvenous right ventricular defibrillation lead. The patient had previously received pacemaker implantation due to sick sinus syndrome. An implantable cardioverter defibrillator (ICD) with a transvenous right ventricular defibrillation lead alone required a high DFT. A subcutaneous array lead improved defibrillation efficacy in combination with a right ventricular lead. These data suggest that a subcutaneous array lead facilitates implantation of an effective ICD lead system in patients requiring a high DFT.
