Changes of STEMI in these ECG, leads are often subtle and are easily missed.

这些心电图中STEMI的变化，导联往往很微妙，很容易被忽略。

At all stages of this process, characteristic changes are produced in the ECG leads directly overlying the regions of myocardium that occluded vessel supplies.

在此过程的所有阶段，ECG导联的特征变化都会直接发生在阻塞血管供应的心肌区域上。

In a given ECG lead, T waves are generally concordant with the QRS complex so that in a lead with a dominant R wave such as v6 the T waves are normally upright.

在给定的心电图导联中，T波通常与QRS波群一致，因此在具有主导R波或v6波的导联中，T波通常是直立的。
