希氏束电图(HBE)是心内电生理检查的重要组成部分,对房室传导阻滞和室内传导阻滞,可用以确定阻滞部位及阻滞性质.我们用该法检查房室传导阻滞患者一例,现报道如下. 一、病例介绍患者男性,27岁,住院号223963.因心电图(ECG)反复交替出现Ⅰ度和Ⅱ度Ⅰ型房室传导阻滞(AVB)一年而入院.无胸闷、胸痛、头晕及晕厥等症状, His (HBE) is an important part of the electrophysiological examination of the heart, atrioventricular block and indwelling conduction block can be used to determine the location of the block and the block.We use this method to check the atrioventricular conduction A case of patients with block, are reported as follows.A case introduction Male patient, 27 years old, hospital number 223963. Due to repeated electrocardiogram (ECG) Ⅰ degree and Ⅱ degree type Ⅰ atrioventricular block (AVB) for one year and admission No chest tightness, chest pain, dizziness and fainting and other symptoms,
