心肌缺血时心电图有什么变化 王建秋 聊城市第四人民医院
典型的心肌缺血发作时,缺血性的ST段压低,包括水平性的、下斜性、还有T波倒置低平或者负正双向；变异性心绞疼多表现为ST段抬高并常伴有高耸的T波和对应导练的ST段下移,严重心机缺血的表现持续性ST段抬高或者高尖的T波持续性的胸疼,这就意识着心肌梗塞的发生,所以心电图呈现ST段明显的压低或者是ST段抬高呈弓背向上性或者T波的倒置意味着心肌梗塞,所以说大家一定要引起重视。

What is the change of ECG in myocardial ischemia
In a typical myocardial ischemic attack, Ischemic ST segment depression, It includes horizontal, downward sloping, and T-wave inversion, low level or negative positive and negative two-way; Most of the patients showed ST segment elevation with high T wave and ST segment depression, Severe myocardial ischemia is characterized by persistent ST segment elevation or high sharp T wave persistent chest pain, That's what we're aware of, So the ECG shows that ST segment is obviously depressed or ST segment is elevated, which means myocardial infarction, So we must pay attention to it.
