临时起搏在永久心脏起搏器安置术中的应用

目的:探讨临时起搏在永久心脏起搏器安置术中的应用.方法:1990年1月至2011年6月我院安置永久性心脏起搏器者,共903例.将安置了临时起搏器的77例设为观察组,未安置临时起搏器的826例设为对照组.比较2组安置永久性心脏起搏器所花费的时间、恶性心律失常发生率及异丙肾上腺素使用比例.结果:手术均获得成功.观察组术中静脉滴注异丙肾上腺素及恶性心律失常的发生比例、手术时间均低于对照组(P＜0.05).结论:对于高度房室传导阻滞、病窦或严重依赖起搏患者,安置临时起搏器能增加永久性起搏器植入手术安全,有效防止术中严重心律失常的发生.

The Application of Temporary Cardiac Pacing in Permanent Pacemaker Implantation

Objective:To investigate the application of temporary pacing in permanent pacemaker implantation.Methods:From January 1990 to June 2011,903 the patients with permanent pacemaker were divided into two groups: Temporary pacemaker group(77 cases) and the group without temporary pacemaker(826 cases).Operative time,the use of isoproterenol and the incidence of Malignant arrhythmia during permanent pacemaker implanted were recorded,the results were analyzed and compared in the groups.Results:All operations were successful.Operative time,the use of isoproterenol and the incidence of malignant arrhythmia in temporary pacemaker group was lower than in the group without temporary pacemaker.Conclusion:For the patients with high degree atrioventricular block,severe sinus node dysfunction or pacemaker-dependent,placement of temporary pacemaker can increase safety of patients in the permanent pacemaker implantation and prevent the occurrence of severe arrhythmias.
