平均心电轴的测量,有助于诊断某些心脏病变(如左或右心室肥厚、左前或左后束支传导阻滞、室内传导阻滞、心肌梗塞、心肌病变等)。目前计算平均心电轴常用查表法。其方法是先求Ⅰ、Ⅲ导联QRS波群振幅高度的代数合,然后在事先计算好的表格上查电轴度数,手续较繁杂。为临床使用方便而制作了由Ⅰ、aVF导联QRS波群计算平均电轴计算器。原理:根据爱氏(Eihthoven)定律和贝莱氏(Bailey)六轴系统原理,选用Ⅰ、aVF导联QRS波群高度代数合在座标图上进行测算,图为Ⅰ、aVF导联在六轴系统中可看做是互相垂
The mean ECG axis is useful for the diagnosis of certain heart conditions (left or right ventricular hypertrophy, left or left bundle branch block, intraventricular conduction block, myocardial infarction, cardiomyopathy, etc.). Calculate the average current ECG table commonly used look-up method. The method is to first seek lead Ⅰ, Ⅲ lead QRS complex amplitude algebra, and then calculate the table in advance to calculate the number of axes, procedures more complicated. For clinical use and made by the Ⅰ, aVF lead QRS complex calculated average electric axis calculator. Principle: According to Eihthoven’s law and Bailey’s six-axis system principle, the selection of Ⅰ, aVF lead QRS wave group height algebra is calculated on the graph, the photo I, aVF lead in the six-axis System can be seen as hanging each other
