介绍非开胸植入埋藏式心脏复律除颤器（ＩＣＤ）治疗２２例患者室性心律失常的临床应用。ＩＣＤ治疗适应证包括：１７例心室颤动患者和５例顽固性室性心动过速患者。基础心脏病为：冠心病１３例，扩张性心脏病７例，致心律失常性右室发育不良２例。２２例患者中２０例成功地植入了非开胸ＩＣＤ（９１％），平均除颤阈值为１６．７±４．６Ｊ。２例未成功患者因除颤阈值偏高而改用开胸植入ＩＣＤ。平均住院时间为７．４±３．３天。并发症为：除颤器囊袋血肿１例，心室电极脱位需重新安放１例。在平均随访１０．１±８个月中，６例患者接受了ＩＣＤ治疗。其中４例患者发生心室颤动，由ＩＣＤ成功地除颤；２例患者发生室性心动过速，由ＩＣＤ发放抗心动过速起搏终止。
To introduce the clinical application of non-thoracic implantable cardioverter defibrillator (ICD) in the treatment of ventricular arrhythmias in 22 patients. ICD treatment indications include: 17 patients with ventricular fibrillation and 5 patients with refractory ventricular tachycardia. Basic heart disease: coronary heart disease in 13 cases, 7 cases of dilated heart disease, induced arrhythmogenic right ventricular dysplasia in 2 cases. Of the 22 patients, 20 had a successful non-thoracic ICD (91%), with an average defibrillation threshold of 16.7 ± 4.6J. Two unsuccessful patients switched to thoracotomy for ICD due to the high defibrillation threshold. The average hospital stay was 7.4 ± 3.3 days. Complications: defibrillator cyst hematoma in 1 case, ventricular electrode dislocation to be re-placed in 1 case. During the mean follow-up of 10.1 ± 8 months, 6 patients received ICD treatment. Ventricular fibrillation occurred in 4 of these patients and defibrillation was successfully performed by the ICD. Ventricular tachycardia occurred in 2 patients and anti-tachycardia pacing was terminated by the ICD.
