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.
我们报告了一例具有高除颤阈值（DFT）的Brugada综合征患者，该患者使用皮下阵列电极导线与经静脉右心室除颤电极导线联合使用以降低DFT。该患者先前因病态窦房结综合征接受了起搏器植入。单独使用经静脉右心室除颤电极导线的植入式心脏复律除颤器（ICD）需要较高的DFT。皮下阵列电极导线与右心室电极导线联合使用可提高除颤效果。这些数据表明，皮下阵列电极导线有助于在需要高DFT的患者中植入有效的ICD电极导线系统。
