Inferior myocardial ischemia can be cured because myocardial ischemia is caused by stenosis or spasm of the coronary arteries, resulting in insufficient oxygen and blood supply to the myocardium and a series of symptoms mainly angina pectoris. In case of myocardial ischemia in the lower wall, the first thing to do is to give an electrocardiogram. On the electrocardiogram, you can see severe depression or arch-back elevation in the ST segment in leads 2, 3 and AVF. In addition, inversion and hyperacusis of the T wave can also clarify the location of the inferior wall. Once this occurs, coronary angiography is used to clarify the coronary lumen stenosis, and if the stenosis is severe, treatment with coronary stenting or surgical open-heart bypass surgery is required, through which the state of myocardial ischemia can be cured radically.
