Which ECG leads show inferior infarction?

Explanation:
Inferior infarction affects the bottom wall of the left ventricle, and the ECG leads that look at that area are II, III, and aVF. When this region is damaged, you typically see ST-segment elevation in those inferior leads, signaling an inferior myocardial infarction (often due to occlusion of the right coronary artery). The other lead groups view different parts of the heart: lateral leads (I, aVL, V5–V6) look at the lateral wall, anterior/septal leads (V1–V3) look at the front of the heart, and aVR is a reference view that doesn’t directly show the inferior wall infarct (and may show reciprocal changes). So the pattern of ST elevation in II, III, and aVF best identifies an inferior infarction.
