Wellens syndrome is characterised by negative or biphasic T waves in V2-V4 leads 
and critical stenosis of proximal part of the left descending coronary artery. 
These ECG changes without atherosclerotic changes in coronary angiography, i.e. 
coronary artery spasm are called pseudo-Wellens syndrome. We describe a patient 
with acute coronary syndrome and pseudo-Wellens syndrome as a cause of 
vasospastic angina. These ECG abnormalities need differentiation with acute 
pulmonary embolism.
