Implantable cardioverter defibrillator (ICD) testing in patients with left ventricular noncompaction (LVNC) at the time of implantation and potential difficulties with ventricular fibrillation (VF) induction/termination in LVNC patients are often not stated in the literature. This report describes the failure of transvenous implantation of an ICD in a 40-year-old patient with LVNC and polycystic kidneys. A high defibrillation threshold (DFT) prevented termination of ICD-induced VF. This case suggests that DFT testing should be considered in any LVNC patient during ICD implantation. The association of LVNC and polycystic kidneys is also discussed.
植入式心脏复律除颤器（ICD）在左心室心肌致密化不全（LVNC）患者植入时的测试，以及LVNC患者中室颤（VF）诱发/终止的潜在困难，在文献中往往未被提及。本报告描述了一名患有LVNC和多囊肾的40岁患者经静脉植入ICD失败的情况。高除颤阈值（DFT）阻碍了ICD诱发的VF的终止。该病例表明，在ICD植入期间，任何LVNC患者都应考虑进行DFT测试。同时也讨论了LVNC与多囊肾的关联。
