Question: 1 / 400

ST segment elevation is a major ECG abnormality associated with:

Low blood pressure

Dehydration

The diagnosis of myocardial infarction

ST segment elevation is a major ECG abnormality that is associated with the diagnosis of myocardial infarction (heart attack). This is because a heart attack can occur when the blood flow to the heart is blocked, leading to damage and death of heart muscle cells. This blockage can be seen on an ECG as ST segment elevation. Option A (low blood pressure) and B (dehydration) are incorrect because they do not directly cause a heart attack or affect the ECG in this way. Option D (anemia) is also incorrect because while it can sometimes be associated with cardiovascular disease, it is not a major abnormality typically seen on an ECG.
