- Key ECG: Hyperacute T-waves in V2-V5, very suggestive of Proximal LAD occlusion, but without ANY ST Elevation except for less than 1 mm in aVL, and 0.25 mm in lead I. There is also minimal STE in aVL with reciprocal STD in II, III, aVF. Notice that there is plenty of R-wave in V2 and V3. This should be an obvious case of acute proximal LAD Occlusion. In this, case the Hyperacute T-waves are preceded by subtle ST Depression in V2 and V3. Thus, they are specifically the hyperacute T-waves called “de Winter’s T-waves.”
