1969年Scherlag等首次用导管电极在心内记录希氏束电图(His bundle electrogram,HBE)获得成功,开拓了房室传导障碍诊断及研究的新领域.此后,这一新技术的应用发展很快,大量实践表明,它在传导阻滞的定位、心脏起博器的应用、某些心律失常的鉴别诊断以及机制研究等方面都有很大临床价值,所以日益受到临床心脏学者和心脏生理学者的重视.但是心内记录法是侵入性方法,对被检者有一定危险,而心导管术又要求复杂的设备和熟练的技术,这就大大妨碍了这一技术的广泛应用.因此很多人都在探索从体表记录希氏束电位的方法.
In 1969, for the first time, Scherlag et al succeeded in recording intracardiac His bundle electrogram (HBE) with a catheter electrode and opened up a new field of diagnosis and research of atrioventricular conduction disorder. Since then, the application of this new technology has developed rapidly , A great deal of practice shows that it has great clinical value in the location of conduction block, the application of pacemakers, the differential diagnosis of certain arrhythmias and the mechanism research, etc. Therefore, it is increasingly accepted by clinical cardiologists and cardiologists However, intracardiac recording is an invasive method that presents a certain risk to the subject and that cardioversion requires sophisticated equipment and sophisticated techniques that greatly hinder the widespread use of this technique. In exploring the method of recording His bundle potential from the surface of the body.
