Negative T Wave in Ischemic Heart Disease: A Consensus Article
T wave followed by ST elevation, and finally the appearance of Q wave with T-wave inversion. Therefore, negative T wave only appears as a late manifestation, when the acute ischemia already has evolved to transmural infarction. Therefore currently, we consider that negative T wave do not appear during the hyperacute phase of ongoing

A normal ECG does NOT rule out any Acute Coronary Syndrome.\爀屲ST segment depression represents ischemia, infarction is possibl\.\爀屲ST segment elevation represents epicardial ischemia, and is presumptive evidence of AMI.\爀屲Since necrosis may occur under a對ll the these situations, a Q wave MI may follow ST elevation, ST depression or ...
