Implantable cardioverter defibrillator (ICD) prevention of sudden cardiac death (SCD) is not absolute and our experience was reviewed to determine the frequency and nature of SCD in this population. The incidence and cause of mortality in 56 consecutive patients, who underwent ICD implantation beginning May 1982 with follow-up through May 19, 1990 were analyzed. Twenty-one patients died, 33% of the mortality was due to SCD, and 52% of deaths may be considered arrhythmic. The cumulative 1, 3, and 5 year SCD survivals were 93%, 89%, and 75%. All seven patients dying of SCD presented initially with SCD, all received previous shocks prior to SCD, and two of the seven patients had devices that were probably inactive at the time of death. We conclude that ICDs reduce but by no means eliminate arrhythmic death, particularly in those at highest risk for SCD. Arrhythmic death remained the most common cause of death in this population.
植入式心脏复律除颤器（ICD）预防心脏性猝死（SCD）并非绝对有效，我们回顾了相关经验，以确定该人群中SCD的发生频率和性质。分析了1982年5月起接受ICD植入且随访至1990年5月19日的56例连续患者的死亡率及死因。21例患者死亡，其中33%的死亡归因于SCD，52%的死亡可被视为心律失常性死亡。1年、3年和5年的SCD累积生存率分别为93%、89%和75%。所有7例死于SCD的患者最初均表现为SCD，所有患者在SCD前均接受过电击，7例患者中有2例在死亡时其装置可能未发挥作用。我们得出结论，ICD可降低但绝不能消除心律失常性死亡，尤其是在SCD风险最高的人群中。心律失常性死亡仍是该人群最常见的死亡原因。
