希氏束电图是描记心内传导系统电位变化的曲线,它能将房室传导与希氏束—浦氏系统的传导区分开来,从而了解正常和异常的房室传导,可以对传导阻滞进行定位诊断,并指导应用心脏起搏器等临床治疗。本文采用无创伤体表叠加法记录100例老年人希氏束电图(简称SHBE),对正常老年人与青壮年SHBE的结果进行了对照分析,并探索其对老年人传导阻滞定位,预激综合征分型的实用价值。 对象和方法 His bundle is a curve that describes changes in the potential of the conduction system in the heart. It distinguishes the conduction of the atrioventricular system from the conduction of the His bundle-system to understand the normal and abnormal conduction of the atrioventricular system, Hysteresis positioning diagnosis, and guide the application of cardiac pacemakers and other clinical treatment. In this paper, 100 cases of SHBE were recorded by non-invasive superficial skin superposition method. The results of SHBE in normal and young adults were compared and analyzed. Practical value of typing of irritable. Objectives and methods
