超急性期T波(hyperacute Twave,HATW)是急性心肌梗死超急期的心电图表现,常出现在ST段抬高之前,早年文献亦称其为直立冠状T波。其表现为高振幅对称性,基底部宽大的正向T波,当同时出现在≥两个相邻导联时,对诊断极早期急性心肌梗死有很高的特异性(排除其他原因后)。 Hypertensive hyperacute T wave (HATW) is an electrocardiogram of acute myocardial infarction (Hypertension), which is often found before ST-segment elevation. Earlier years, HATW was also called upright coronary T wave. It exhibits high amplitude symmetry and a generous forward T-wave at the basal portion that is highly specific for the diagnosis of very early acute myocardial infarction (when other causes are excluded) when present in ≥ two adjacent leads.
