ST elevation in leads V1-V4 is indicative of which wall myocardial infarction?

• A. Inferior wall MI
• B. Lateral wall MI
• C. Anterior wall MI
• D. Posterior wall MI

Answer: (C)

ST elevation in leads V1-V4 primarily indicates an anterior wall myocardial infarction. These leads correspond to the anterior part of the heart, which is supplied by the left anterior descending artery. When there is ST elevation in these leads, it suggests that there is significant ischemia and damage to the myocardium in the anterior wall region, typically due to a blockage in this artery. In the context of myocardial infarction, the location of ST elevation in the electrocardiogram (ECG) is crucial for diagnosing the specific area of the heart that is affected. The anterior wall is critical for overall cardiac function and is associated with a higher risk of complications, making early recognition of ST elevation in these leads vital for prompt intervention.
