Do electrocardiogram myocardial ischemia is how to return a responsibility

The causes of myocardial ischemia include hypertension, vasospasm, coronary atherosclerotic heart disease, etc. The specific analysis is as follows:

1. Hypertension

long-term uncontrolled hypertension will increase the burden on the heart and damage coronary endothelial function, leading to arteriosclerosis and coronary artery stenosis, and then cause myocardial

ischaemia.2. Vasospasm

If the patient's blood vessels should spasm for various reasons, the vascular lumen will suddenly narrow, reducing the amount of blood entering the blood vessels, thus causing myocardial

ischaemia.3. Coronary atherosclerotic heart disease

Coronary atherosclerotic heart disease may form a large number of thrombosis, leading to coronary artery blockage, resulting in myocardial ischemia.
