摘要 2例恶性室性心律失常患者接受埋藏式心脏复律除颤器(ICD)治疗，分别对其进行了42，54个月随访。ICD储存资料证实心律失常事件148次，启动治疗程序28次。其中电击除颤12次，采用抗心动过速起搏转复14次，均为首次成功，成功率100%；发生误放电2次，占治疗程序的7.1%(2/28)。其余120次事件自行终止。术后口服奎尼丁可减少室性心动过速的发生，缩短发作时间。其中1例已更换ICD，原导管系统仍符合使用条件。误放电原因与突发性标准未设置及设置不当有关。患者对电击的不适感与ICD电击条件无关，系术后心理障碍所致。

Abstract Two patients with malignant ventricular arrythmia received implantable cardioverter-defibrillator was followed up 42,54 months respectively.The storage data revealed 148 episodes of arrythmic events was detected by ICD.The treatment programs were triggered 28 times.In which,electrical defibrillation cardioversion was given 12 times and 14 times of ATP cardioversion were used.The successful rate was 100 percent.All terminated successfully by the first treatment.Wrong discharge occurred twice which was 7.1%(2/28) of total treatment programs.The other 120 times of arrythmic events were nonsustained which were terminated spontaneously.Oral administration of Qinidine was given after implantation to decrease ventricular tachycardia and shorten its duration.One patient changed ICD.The original catheter system TB could be used continuously.The reason for wrong discharge was related to nonpresetting and wrong presetting of the criterion for sudden onset.The patients feeling of discomfort towards electric shock had become more and more significant.This was caused by post-operative psychological disturbance and wasnt related to ICD cardioversion condition.
