What does ST-T change mean

summary

In recent days, our company has arranged physical examination for our employees. When doing physical examination, we need to do ECG. The doctor's examination results are: sinus rhythm, ST-T changes. I'm a little puzzled, so I checked the information on the Internet. Below, I'll share with you the meaning of ST-T change.

What does ST-T change mean

First of all: This is only an index parameter of ECG. The change of ST-T segment generally indicates that there is a certain lack of blood supply to the heart, but it can not be determined simply from this item. It can only be suspected. It also needs to be combined with some daily symptoms of patients to have a comprehensive look. Some normal people also have very mild ST-T segment changes.

Second, coronary heart disease does cause ST-T changes, such as chest tightness, chest pain, precordial discomfort, but it is not the only cause of myocardial ischemia. Other diseases, including cardiac syndrome X, myocarditis, cardiomyopathy, myocardial bridge and idiopathic ST-T changes, can also cause ST-T changes in ECG. In addition to ECG, if the patient has obvious symptoms, we should further improve the examination to see the situation.

Finally: the ST-T change of electrocardiogram is the landmark change of coronary heart disease, because the lumen of coronary artery becomes narrower and blocked after the occurrence of atherosclerosis, or the function changes and spasm (vascular tension, unnatural contraction), both of which can lead to myocardial ischemia and hypoxia. Therefore, coronary heart disease is also called ischemic heart disease, and ST-T change appears on electrocardiogram.

matters needing attention

In the physical examination, once the ECG ST-T changes, we should carefully listen to the doctor's advice, in order to avoid causing unnecessary mental burden.
