In a 12 lead EKG, which finding indicates an Anterior wall infarction?

An anterior wall infarction is characterized by changes in specific leads on a 12-lead EKG, primarily involving the left anterior descending artery's territory. The leads that typically reflect an anterior wall infarction include V2, V3, and V4. Recognizing these lead abnormalities is essential for diagnosing a heart attack in the anterior wall of the heart.

The correctness of identifying an anterior wall infarction directly correlates to understanding the myocardial areas supplied by different coronary arteries and how these regions correlate with the changes seen in EKG leads. In this context, option C clearly indicates an anterior wall infarction, which is directly tied to the leads that show ST-segment elevation or Q waves indicative of ischemia or necrosis in the anterior cardiac regions.

The other options represent different infarction locations, each associated with changes in other leads. For instance, lateral wall infarctions involve leads I, aVL, V5, and V6, while inferior wall infarctions typically manifest in leads II, III, and aVF. Septal wall infarctions affect leads V1 and V2. Understanding these specificities helps in accurately diagnosing the type of infarction based on EKG findings.
