Wellens' syndrome is characterized by symmetrically inverted T-waves in the 
precordial leads suggestive of impending myocardial infarction due to a critical 
proximal left anterior descending (LAD) stenosis. We describe three unusual 
cases of patients with such electrocardiographic abnormality in which coronary 
angiography ruled out the presence of critical coronary stenosis and cardiac 
magnetic resonance imaging excluded the presence of acute or chronic myocardial 
infarction.
