ST elevations in leads V1–V4 indicate involvement of which territory?

ST elevations in the anterior chest leads map to the front wall of the left ventricle. Leads V1 through V4 view the anterior/septal region, so ST elevation there reflects an anterior transmural infarct, usually from occlusion of the left anterior descending artery. This localization is distinct from inferior (II, III, aVF), lateral (I, aVL, V5–V6), or posterior changes, which present with different lead patterns (posterior infarction often shows reciprocal changes in the anterior leads and requires posterior leads to confirm). So the pattern points to an anterior STEMI.
