• Site(s) of infarct in the heart often correlates with the leads where abnormal ECG tracing (e.g. ST elevation, pathologic Q wave) is found.
• As illustrated below (leads color-coordinated with affected myocardial walls), ST elevation +/- pathological Q wave in--
V5-6 + I, aVL = lateral MI
V1-2 = septal MI
V3-4 = mid-anterior MI
V1-6 = anterior MI
II, III, aVF = inferior MI
V1-2 + V3R-4R = right ventricular MI
V7-9 = posterior MI
