What does ST segment elevation indicate in an ECG?

• A. Normal Heart Function
• B. Myocardial Injury
• C. Bradycardia
• D. Cardiac Hypertrophy

Answer: (B)

ST segment elevation on an electrocardiogram (ECG) is an important indicator of myocardial injury, often associated with conditions such as acute myocardial infarction (AMI) or other forms of heart muscle damage. When there is an elevation in the ST segment, it typically suggests that a part of the heart is receiving insufficient blood supply due to a blockage in a coronary artery, leading to ischemia and subsequent injury to the myocardial tissue. This elevation represents the abnormal electrical activity in the heart associated with the damage. Clinically, identifying ST segment elevation allows healthcare providers to potentially initiate rapid interventions to restore blood flow and minimize heart tissue damage, such as administering medications or performing procedures like angioplasty. The presence of ST segment elevation is therefore critical for diagnosing and managing acute coronary syndromes, making it a key marker for myocardial injury.
