急性下壁心肌梗死合并高度AVB时临时起搏治疗手术方法探讨

Study of Operative Approach of Temporary Cardiac Pacing Therapy in Patients with Acute Inferior Wall Myocardial Infarction Complicated by High Degree Atrioventricular Block

目的分析、总结急性下壁心肌梗死合并高度房室传导阻滞的患者经静脉心脏临时起搏治疗的手术方法.方法选择112例因为急性下壁心肌梗死合并高度房室传导阻滞需要进行经静脉心脏临时起搏治疗的患者,观察研究经静脉心脏临时起搏治疗不同手术方法的安全性、有效性及与并发症的关系.结果全组60例使用普通临时起搏电极导管的病例中出现3例心脏压塞,52例使用漂浮临时起搏电极导管的病例中未出现严重并发症.结论在急性下壁心肌梗死的患者出现高度房室传导阻滞时进行经静脉心脏临时起搏治疗时,选择漂浮临时起搏电极导管安全、有效并且可以减少心肌穿孔等严重并发症的发生.

Objective This study was purposed to analyze and summarize the vein temporary cardiac pacing therapy in patients with acute inferior wall myocardial infarction complicated by high degree atrioventricular block （AVB） . Methods One hundred and twelve patients with acute inferior wall myocardial infarction complicated by high degree AVB were selected as observation and research subjects, and they were treated by vein temporary cardiac pacing therapy. The safety, availability of different kinds of this surgical methods and the relationship between these surgical methods and complication were observed. Results Three out of 60 patients who were treated by ordinary temporary pacing electrode catheter were suffering from cardiac tamponade. No serious complications occurred when 52 patients were treated by floating temporary pacing electrode catheter. Conclusion Floating temporary pacing electrode catheter have already proved safe and effective in the treatment of acute inferior wall myocardial infarction complicated by AVB, and it could decrease the incidence of serious complications such as myocardial perforation.
