What does acute ST elevation indicate in an EKG?

Acute ST elevation on an EKG typically indicates myocardial infarction or acute injury to the heart muscle. This elevation signifies that there is a significant disruption in the normal electrical activity of the heart, often due to a blockage in one or more coronary arteries, resulting in damage to the myocardial tissue. The presence of ST elevation suggests that some part of the heart is not receiving enough blood and oxygen, which is crucial for the heart to function properly.

In diagnosing an ST elevation myocardial infarction (STEMI), criteria often include the elevation of the ST segment in two or more contiguous leads, which reflects the location and extent of the cardiac damage. Prompt identification of acute ST elevation is vital, as it requires immediate medical intervention to restore blood flow and minimize heart damage.
