Abstract

A method is presented for the non-invasive recording of His bundle electrical activity from the body surface in man. Several bipolar ECG leads were employed: precordial, Frank "x" and Frank "z". Signals were filtered (30-300 Hz), highly amplified (5 x 104) and averaged. Digital averaging was performed on line by a microcomputer (OTE Biomedica Neuroaverager mod. 1172). Surface investigation was performed in 10 patients affected by different conduction pathology simultaneously with HBE recordings for diagnostic purpose and in 5 normal volunteers only incruently. Highly repeatable electrical deflections (B waves) were recorded in the PR segment. In all patients a good correspondence between surface (B wave) and intracardiac (H wave) was found. Atrial pacing and pharmacological test were used in order to ascertain the real source of B wave.

摘要

本文介绍了一种从人体体表无创记录希氏束电活动的方法。使用了多个双极心电图导联：胸前导联、弗兰克“x”导联和弗兰克“z”导联。信号经过滤波（30 - 300Hz）、高倍放大（5×10⁴）并进行平均处理。数字平均由微型计算机（OTE Biomedica Neuroaverager mod. 1172）在线完成。对10例患有不同传导病理的患者进行了体表研究，同时记录希氏束电图用于诊断目的，目前仅对5名正常志愿者进行了研究。在PR段记录到了高度可重复的电偏转（B波）。在所有患者中，均发现体表（B波）与心内（H波）之间有良好的对应关系。采用心房起搏和药理学试验来确定B波的真正来源。
