Wellens' syndrome

Wellens' syndrome

the electrocardiographic signs of critical proximal left anterior descending coronary artery stenosis in patients with unstable angina. The signs are: normal or minimally elevated enzyme; little or no S-T segment elevation; no loss of precordial R waves; and progressive, deep, symmetric inversion of the T waves in leads V2 and V3, and sometimes in other leads. The signs are seen when the patient is without pain and represent reperfusion following transient occlusion.
