心肌缺血除表现为ST段压低和T波倒置,也可仅表现为ST段延长和T波幅度降低。在无上述表现的情况下,ST/T角度对心肌缺血的存在也有一定诊断意义。
In addition to the performance of myocardial ischemia ST segment depression and T wave inversion, but also only for the ST segment elongation and T wave amplitude decreased. In the absence of such performance, ST / T angle of the existence of myocardial ischemia also has some diagnostic significance.
