目的　植入型心律转复除颤器 (implantablecardioveterdefibrillatorICD)是目前预防心脏性猝死最有效的措施。本文观察我院8例次植入型心律转复除颤器患者的临床疗效及随访情况。方法;;自1996年7月至2003年9月;;共有7例患者(其中1例更换1次)在我院成功安装了ICD。7例患者中4例为扩张性心肌病;;1例为长QT间期综合症;;1例为多形性室性心动过速;;另1例为完全性右束支传导阻滞伴恶性室性心律失常;;Brugada综合征不能排外。所有患者均记录到VT或/和VF;;其中5例患者有晕厥史。分别随访2个月～7年。结果;;7例患者均成功经静脉安置或更换ICD。除颤阈值均在25J以下。随访期间共发生室性快速心律失常16次;;其中室性心动过速10次;;室颤6次;;均成功中止。其中抗心动过速起搏终止10次;;除颤6次。误感知窦性心动过速发生ATP4次;;误感知室上性心动过速发生除颤2次。患者均正常生活至今。结论;;ICD治疗效果肯定;;但需加强随访;;及时调整参数;;同时需注意药物的辅助治疗 Objective Implantable cardioverter defibrillator (implantable cardioveterdefibrillator ICD) is the most effective measure to prevent sudden cardiac death. This article observed 8 cases of our hospital implantable cardioverter defibrillator clinical efficacy and follow-up. Method ;; from July 1996 to September 2003 ;; a total of seven patients (one of which was replaced once) in our hospital successfully installed ICD. 4 of 7 patients were dilated cardiomyopathy; 1 was long QT syndrome; 1 was polymorphic ventricular tachycardia; and the other 1 patient was complete right bundle branch block Malignant ventricular arrhythmia ;; Brugada syndrome can not be excluded. All patients were recorded VT or / and VF ;; of which 5 patients had a history of syncope. Were followed up for 2 months to 7 years. Results; 7 patients were successfully placed or replaced by intravenous ICD. Defibrillation thresholds are below 25J. A total of 16 cases of ventricular tachyarrhythmia occurred during the follow-up period. Among them, ventricular tachycardia was 10 times and ventricular fibrillation was 6 times. Which anti-tachycardia pacing terminated 10 times; defibrillation 6 times. Misdiagnosis of sinus tachycardia occurs ATP4 times ;; false sense of supraventricular tachycardia occurred defibrillation 2 times. Patients are normal life so far. Conclusion; ICD treatment effect ;; but need to strengthen follow-up ;; timely adjustment of parameters; at the same time need to pay attention to drug adjuvant therapy
