Myocardial ischemia can be detected. Myocardial ischemia can be detected by routine electrocardiography, coronary angiography, ambulatory electrocardiography and echocardiography.
1. Conventional electrocardiogram: ST-segment depression and T-wave inversion can be seen in patients with myocardial ischemia after conventional electrocardiogram.
2. Coronary angiography: Coronary stenosis can lead to myocardial ischemia. Coronary angiography can observe whether the coronary vessels are narrowed and whether it will cause myocardial ischemia.
3. Dynamic electrocardiogram: Dynamic electrocardiogram can reflect the frequency, duration and severity of myocardial ischemia episodes, and is an important way to diagnose myocardial ischemia.
4. Echocardiography: Patients with myocardial ischemia may see limited ventricular wall motion abnormalities on echocardiography.
Patients are advised to go to local specialized hospitals as soon as possible to clarify or exclude the diagnosis.
