Wellens syndrome

Wellens syndrome is a result of critical stenosis of the left anterior descending artery. There two types of Wellens syndrome: type A is characterized by biphasic T waves with positive initial part and negative terminal part in leads V2 and V3. Also, it may be seen in all precordial leads. Type B is characterized by deeply and symmetrically inverted T waves in same leads as type A. Type B is 3 times more frequent than type A.
There are following criteria of the Wellens syndrome:
- biphasic T waves with positive initial part and negative terminal part, so-called type A, or deeply and symmetrically inverted T waves, so called type B.
- no ST segment elevation or less than 1 mm of ST segment elevation
- no pathological precordial Q waves and no poor precordial R wave progression
- recent history of angina
- ECG pattern presents in a pain-free state.
In the case of well-timed percutaneous coronary intervention with reperfusion of the left anterior descending artery, the patient’s prognosis is good, significant morbidity and mortality may be avoided.
