ST elevations in leads I, aVL, and V1-V4 and ST depressions in leads II, III, and aVF, suggests the origin of occlusion in the proximal portion of the LAD.
ST elevations in leads V3-V6 and no ST-segment depressions in leads II, III, and aVF, suggests the origin of occlusion in distal part of the LAD.
ECG 1 STEMI anterior (ST elevations in V1-V4, ST depressions in inferior leads)
ECG 2 STEMI anterior (ST elevations in V1-V4, ST depressions in inferior leads, RBBB) - proximal LAD occlusion was documented in cath lab.
