How to never miss Wellen's syndrome 

It’s my quote board - I try to write a new one each month. That one said “There’s no such uncertainty as a sure thing”. (Robert Burns) 😊

Good question! I think it depends on the timing and degree of reperfusion. Wellens type A has terminal T inversion, suggesting early reperfusion after an LAD occlusion that has partially resolved. Wellens type B is likely the evolution over time after reperfusion, as the T wave inversion becomes symmetrical and complete.
