(wellens =subacute LAD occlusion (there are 2 types of wellen)
de winter=ACUTE LAD OCCLUSION may equal STEMI
occures also in circumflex & diagonal
URGENT CATH
de Winter's T-waves really represent very tight subtotal occlusion of the LAD. Complete occlusion results in ST Elevation. Very tight stenosis results in subendocardial ischemia with diffuse ST depression and STE in aVR. de Winter's is a point halfway between these two: a hybrid of STEMI and diffuse ST depression with STE in aVR.
