This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: C.V.S, Subject name: Medicine
A 58-year-old diabetic came with chest pain, ECG shows ST elevation in II, III and AVF leads. Inference would be 
Select and explain. 
A. Inferior wall MI, B. Anterior wall MI, C. Lateral wall MI, D. Posterior wall MI
A: Inferior wall MI
Answer: A: Inferior wall MI 
Explanation: Inferior wall ischemia produces changes in leads II, III, and AVF.Acute transmural anterior (including apical and lateral) wall ischemia is reflected by ST elevations or increased T-wave positivity in one or more of the precordial leads (V1-V6) and leads I and aVL"Posterior" wall ischemia (usually associated with lateral or inferior involvement) may be indirectly recognized by reciprocal ST depressions in leads V1 to V3 (thus constituting an ST elevation "equivalent" acute coronary syndrome). Right ventricular ischemia usually produces ST elevations in right-sided chest leads Ref: Harrison 19e pg: 1456
