A Patient With Chest Pain and Hyperacute T Waves

Early/Subtle electrocardiography features of acute coronary syndrome and ST-Segment elevation myocardial infarction

“…Hyperacute T-waves are one of the earliest manifestations of STEMI in myocardial infarction. [ 5 6 7 8 9 ] Hyperacute T-waves can be normal variants in young Negro adults. A study done by Collins et al .…”

Proposed new classification for acute coronary syndrome: Acute coronary syndrome requiring immediate reperfusion

“…16 Hyperacute T waves It is considered an early sign of STEMI in the context of a patient with symptoms of acute coronary syndrome. 17,18,26 J-point deviation and ST-upslope in V1-V6 with symmetrical tall, positive T waves, often with 1-2 mm ST-elevation in aVR (de Winter pattern)…”

“…Similarly, those patients with acute myocardial infarction and total coronary occlusion (TIMI 0/1 flow) had the highest in-hospital mortality (8.6%), compared with 6.3% in patients with acute myocardial infarction and TIMI 2/3 flow, and 2.9% in patients with unstable angina and TIMI 2/ 3 flow (p = 0.006). 16 Another of the electrocardiographic manifestations associated with an acute coronary occlusion without ST-elevation is hyperacute T waves which are associated with an occlusion of the left anterior descending artery, 17,18,26 and this scenario may also benefit from an immediate reperfusion strategy.…”
