ST-segment elevation

ST-segment elevation is a change seen on an electrocardiogram (ECG) that indicates part of the heart muscle isn't getting enough oxygen, often due to a blockage in a coronary artery. It appears as an abnormal upward shift in a specific section of the heart's electrical activity. This finding can signal a serious condition called a heart attack, where immediate medical attention is needed to restore blood flow. Recognizing ST-segment elevation helps healthcare providers diagnose and treat potentially life-threatening heart problems promptly.
