Cardiac axis is the net direction of electrical activity during depolarization.
心电轴是去极化过程中电活动的净方向。
医学英语 心内科
Cardiac axis can be determined by examining the 6 limb leads, which look at the heart from different angles in a vertical plane.
心脏轴可以通过检查6个肢体导联来确定,这些导联在垂直面上从不同角度观察心脏。

Electrocardiography
Electrocardiography (ECG or EKG*) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.
These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle depolarizing during each heartbeat.
It is a very commonly performed cardiology test.
