A case study: I had seen a patient in 1996, when I was working as Emergency Consultant in a corporate hospital, a 45-year-old male who had an ECG done by a GP, on the previous day showing Tall and symmetrical T wave in V1 to V4. It was considered as normal, the next day when he came to me, he developed typical hyper acute changes and was admitted in the ICU and treated accordingly. At that time itself I have made the finding of previous ECG abnormal and made a paper. Points of importance : Hyper acute T waves were tall and, most important, symmetric in chest leads is now a feature of ASMI.
The normal T wave is asymmetric, with a slower upstroke and faster downstroke. The hyperacute T wave is symmetric—ie, it has an upstroke and downstroke that are the same. This is the first ECG change of an acute transmural (ST segment elevation) myocardial infarction (STEMI) of the anterior wall.…
