1221例有症状的致命性室性快速心律失常患者植入第3代复律去颤器,随机分组:A组616例经胸植入心外膜导联,B组605例经静脉插入心内膜导联。这类复律去颤器兼有起搏、复律、去颤、心律失常事件记忆和心动过速非介入性诱发的功能。 部分患者一种导联植入困难,改用另一种导联。616例植入心外膜导联,614例获得成功(99.7％);686例植入心内膜导联,605例
1221 patients with symptomatic and fatal ventricular tachyarrhythmias were implanted with a third-generation cardioverter defibrillator and were randomly assigned to receive 616 cases of transthoracic epicardium leads in group A and 605 cases in group B through the vein Film lead. These types of cardioverter defibrillators both pacing, cardioversion, defibrillation, arrhythmia event memory and tachycardia induced by non-interventional function. Some patients with a lead implants, switch to another lead. 616 cases were implanted with epicardial leads, 614 cases were successful (99.7%); 686 cases were implanted with endocardial leads and 605 cases
