Sinus rhythm, ST segment changes are generally considered to be associated with myocardial ischemia, acute ST-segment elevation myocardial infarction, early repolarization syndrome, etc., generally need further blood infarction three markers, cardiac ultrasound, coronary CTA or angiography and other tests.
1. Myocardial ischemia: If the patient has symptoms such as chest tightness, panic, etc., and the ST segment of ECG is shifted downward by >0.05mv, most of them suggest that there is myocardial ischemia, and the deeper the downward shift accompanied by the patient’s symptoms continue to be unrelieved, which indicates that there may be coronary artery stenosis, and it is necessary to carry out further CTA or angiography, and implantation of a cardiac stent will be required when necessary if there is severe stenosis of the blood vessels.
2. Acute ST-segment elevation myocardial infarction: patients have symptoms such as chest tightness, crushing chest pain, sweating, panic, etc. The ST-segment of electrocardiogram is elevated upward in a bow-back position, which may be accompanied by pathological Q-wave and T-wave inversion, so it is necessary to carry out further examination of three markers of infarction, cardiac ultrasound and coronary angiography to clarify the situation of blood vessels, and then carry out interventional surgery as soon as possible.
3. Early repolarization syndrome: it can be seen in normal people, mostly related to autonomic dysfunction, the ECG suggests that the ST segment is elevated bow-back downward, and it will never change, and most of the patients do not have any obvious discomfort, generally, they can be further examined by the three markers of infarction, cardiac ultrasound, and if there is no combination of other cardiac diseases, it can be observed for the time being.
If the patient’s electrocardiogram suggests sinus rhythm, ST segment changes, it is recommended to go to the hospital as soon as possible, to clarify the cause, and follow the doctor’s instructions for treatment.
