On the other hand, ST-segment depression occurs when normal muscle is located between the injured tissue and the corresponding electrode. Chronic ST-segment elevation indicates the existence of a large infarction, mainly anteriorly, usually with ventricular aneurysm. Coronary artery disease (see ...

ST elevation indicates infarction. ST depression is normally due to ischaemia. ST segment depression may also be seen in digoxin toxicity. Here the ST depression will be downsloping (sometimes known as the “reverse tick” sign). NB: High-takeoff ...
