The ST segments in all leads are expected to lie on the isoelectric line.

所有导联ST段均应位等位线上。

It is normally flat or isoelectric.

它通常是平或等电。

However, the classical ECG abnormalities associated with ischemia are depression of the ST segment below the isoelectric line.

然而，与缺血相关典型心电图异常是ST段在等电线以下压低。

The axis line is perpendicular to the direction of the isoelectric lead.

轴线等电导线方向。

Somewhere in between, usually from V3 to V4, it is isoelectric, with equal positive and negative deflections.

介两者之间某个位置，通常从V3到V4，它是等电，具有相等正负偏转。

The isoelectric lead method: this method consists of finding the isoelectric lead- the one with zero, or nearest to zero net amplitude.

该方法包括寻找等电导联，即净振幅为零或接近零等电导联。

Impulses moving at a 90 degree angle relative to a lead produce an isoelectric, or equiphasic result with positive and negative deflections of similar amplitude.

相对导联以90度角移动脉冲产生等电或等相结果，其正、负偏转幅度相似。

In the minutes following a hyperacute T wave changes, the ST segments in leads overlying the myocardial region deprived of arterial blood supply begin to rise above the isoelectric line.

超急性T波改变后几分钟内，心肌缺血区导联ST段开始高等位线。
