Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...
Wellens was a student Professor Dirk Durrer in Amsterdam and participated in the early development of programmed electrical stimulation of the heart in patients with Wolff–Parkinson–White syndrome. In these patients, cardiac arrhythmias were shown to be initiated and terminated by critically timed premature beats.
Wellens' syndrome is caused by the injury or blockage of the left anterior descending artery, therefore resulting in symmetrical T wave inversions from V2 to V4 with depth more than 5 mm in 75% of the cases. Meanwhile, the remaining 25% of the cases shows biphasic T wave morphology. ST segments remains neutral in this syndrome.

The phenomena [sic] of false suns which sometimes attend or dog the true when seen through the mist (parhelions). In Norfolk a sun-dog is a light spot near the sun, and water-dogs are the light watery clouds; dog here is no doubt the same word as dag, dew or mist as "a little dag of rain" (Philolog. Soc. Trans. 1855, p. 80). Cf. Icel.

Postecoglou’s bullishness about his trophy-winning past may have been music to Spurs supporters’ ears. Yet if his version of second-season syndrome ends, it invites the question of what comes ...
Although considerable effort has been made to improve automated ECG algorithms, the sensitivity of the automated ECG interpretation is of limited value in the case of STEMI equivalent [6] [7] as for example with "hyperacute T waves", [8] de Winter ST-T complex, [9] Wellens phenomenon, Left ventricular hypertrophy, left bundle branch block or in ...
