Core Tip

Core Tip: Wellens syndrome, an electrocardiogram (ECG) pattern seen in high-risk patients with unstable angina pectoris, is characterized by inverted or biphasic T-waves that change into positive or pseudo-normalized waves at precordial leads when the patient experiences an angina attack. We report a case of Wellens syndrome in which we recorded the entire process of ECG evolution. We found that pseudo-normalized T-waves reflected the hyperacute T-waves of ST-segment elevation myocardial infarction (STEMI), which are higher and more symmetrical than normal postoperative T-waves. These pseudo-normalized T-waves may be a manifestation of unstable angina pectoris developing into the hyperacute phase of STEMI.
