自1981年Scheinman等首先使用经导管心内电灼法阻断希氏束安置永久性人工心脏起搏器治疗室上性心动过速(SVT)以来,心内电灼法控制快速性心律失常又有了许多突破性进展。本文拟就该技术的基本现状作一概述。概况利用电灼的技术阻断希氏束最早源于Beazell研究小组。他们将连于除颤器的套针定位于狗的房室交界区,使用电能闭胸切断希氏束获得成功。但因套针质硬,又缺乏心腔内电图定位,不仅形成慢性完全性房室传导阻滞(CCHB)的成功率低,且可致心房穿孔和间隔血肿等严重并发
Since Scheinman et al. First used a catheterized intracardiac electrocautery procedure to block a Hispano-permanent permanent pacemaker in the treatment of supraventricular tachycardia (SVT) in 1981, the electrocardiogram method used to control tachyarrhythmia There are many breakthroughs. This article intends to give an overview of the basic status of the technology. Overview The use of electrocautery technology to block His bundle originated in the Beazell research team. They will be connected to the defibrillator trocar positioning in the dog’s atrioventricular junction area, the use of electric energy to cut off His bundle His chest success. However, due to the trochanter hard and lack of intracardiac mapping, not only the formation of chronic complete atrioventricular block (CCHB) the success rate is low, and can cause atrial perforation and septal hematoma and other serious complications
