ST elevation

ST elevation refers to a change seen on an electrocardiogram (ECG) where the height of the ST segment, part of the heart's electrical pattern, is abnormally increased above the baseline. This often indicates that a portion of the heart muscle is not getting enough blood flow, typically due to a blockage in a coronary artery, and can signal a heart attack. Recognizing ST elevation helps healthcare providers quickly assess and treat potentially life-threatening heart issues.
