T-wave inversions in inferior ST-elevation myocardial infarction - A case of “inferior Wellens sign”

Although T-wave inversions are nonspecific, in the appropriate clinical setting, the pattern of negative biphasic T-waves or T-wave inversion in V2-V3 can indicate critical stenosis of the left anterior descending coronary artery (i.e. “anterior Wellens sign”). Recently tall T-waves in V2-V3 have been reported in association with posterior reperfusion (i.e.“posterior Wellens sign”). Less commonly, negative biphasic T-waves or T-wave inversions in the inferior leads have been reported in association with critical stenosis o f the right coronary artery (RCA) or left circumflex artery (LCx).
