希氏束电图是房室束激动的电位图,它对认识心律失常的机理,提高心律失常的诊断与防治水平,具有重要意义,因而在心电图学和心脏电生理学研究工作中是不可缺少的组成部分。一、希氏束电图的记录方法希氏束激动的电信号很微弱,不是常规心电图记录方法所能得到,目前临床上记录希氏束电图有两类方法,即导管法和体表法。1.导管法:把电极制成导管的形式,从血管内插入心腔,直接接触希氏束,以记录其激动电波。Scherlag 于1968和1969年分别描述了在动物和人体用电极导管经心腔内记录希氏束电图的方
His bundle-beam electrogram is a potentiodynamic graph of atrioventricular bundle, which is of great significance for understanding the mechanism of cardiac arrhythmia and improving the diagnosis and prevention of arrhythmia, and thus it is indispensable in the research of electrocardiogram and cardiac electrophysiology component. First, the His sonogram recording method His bundle beam electric signal is very weak, not the conventional ECG recording methods available, currently there are two methods of recording His bundle beam method, that is, catheter and surface method . 1. Catheter method: the electrode made of catheter form, inserted into the heart chamber from the blood vessels, direct contact with His bundle, to record the excited waves. Scherlag described in 1968 and 1969, respectively, in animals and the human body by catheterization of His
