Background: Wellen's syndrome is a form of acute coronary syndrome associated with proximal left anterior descending artery (LAD) stenosis and characteristic electrocardiograph (ECG) patterns in pain free state. The abnormal ECG pattern is classified into type A (biphasic T waves) and type B (deeply inverted T waves), based on the T wave pattern seen in the pericodial chest leads.
