[Wellens's syndrome -- the ominous T-waves]. / Zespól Wellensa -- grozne oblicze zalamków T.

ABSTRACT

We describe three patients with Wellens's syndrome biphasic T-waves or deeply inverted T-waves in the precordial leads plus a history of acute coronary syndrome without serum marker abnormalities. Wellens's syndrome is due to critical stenosis of the proximal left anterior descending artery and there is a high risk for anterior wall myocardial infarction and/or sudden cardiac death within a few weeks. Early coronary angiography with subsequent PCI or CABG should be performed in these patients. The T-wave changes usually occur during a pain-free interval but resolve within 12 months after revascularisation.
