In the first couple days to weeks, there can be ST segment elevations and PR segment depressions.

在数天或数周内，心电图可见ST段抬高和PR段压低。

While ST segment elevation generally resolves within days and T-wave inversion within weeks following the infarction.

而ST段抬高一般在梗死后几天内消失，T波倒置一般在梗死后几周内消失。

In the great majority of these cases, this does not result in ST segment elevation on the ECG.

在大多数情况下，这不会导致心电图上的ST段抬高。

Pericarditis causes a characteristic " saddleback" ST segment elevation and PR segment depression in all leads except aVR and V1, where the reverse - ST depression and PR elevation – are seen.

心包炎导致除aVR和V1外的所有导联，均呈特征性“鞍背” ST段抬高和PR段下降，aVR和V1可见ST段压低和PR段抬高。

Peaked T-waves, ST segment elevation, and alterations to the terminal portion of the QRS complex are the early changes of acute myocardial infarction secondary to complete occlusion of a coronary arterial vessel.

T波尖峰，ST 段抬高，以及QRS波群终末部分改变，均是继发于冠状动脉血管完全堵塞后的急性心肌梗死的早期改变。
