When you see ST elevations isolated to V2–V3, the most typical culprit is the Left Anterior Descending (LAD) artery, as these leads generally look at the anterior/septal region. An LCx occlusion more classically causes ST elevations in the lateral leads (I, aVL, V5, V6), not just T-wave inversions. Sometimes lateral leads (I, aVL, V5, V6) will show T-wave inversions in response to an anterior wall injury (especially if the infarct extends a bit more laterally). While there can be rare anatomic variants or wrap-around LADs that create atypical ECG findings, the “classic teaching” and by far the most likely scenario is that ST elevation in V2–V3 = LAD occlusion. T-wave inversions in lateral leads (I, aVL, V5, V6) are more likely reciprocal or secondary changes rather than the hallmark of an LCx infarct.
While you had a good explanation, please resubmit with proper citation so we can crosscheck. Thank you.
