Negative T waves in electrocardiography have been widely studied. We presents a case of Wellens' syndrome which is a pattern of global inverted T waves with QT prolongation on ECG due to transient proximal LAD occlusion and pointed out other differential diagnosis.

Takayasu arteritis is a form of vasculitis that involves the aorta, its major branches, and the pulmonary arteries. Coronary artery involvement is not uncommon, and most frequently includes the ostia and proximal segments. ⋯ However, recent advances in imaging modalities-including magnetic resonance angiography, computed tomography (CT), sonography, and fluoro-deoxyglucose positron emission tomography (FDG-PET)/CT Isobe (2013) [2]-have facilitated earlier and more accurate diagnoses of this condition. Here we report a case in which imaging revealed stenosis in the ostia of the coronary artery.
