ST segment changes found on ECG usually indicate the presence of myocardial ischemia. Most of the ST segment changes caused by physiological factors and some pathological ST segment changes can be normalized. 1. ST segment changes caused by physiological factors: such as irregular work and rest, fatigue, stress, etc. may lead to ST segment elevation or depression, and ST segment changes can be normalized by changing bad habits and relaxing the mood; however, there are some congenital ST segment abnormalities, which are mostly normal variations, and will not be restored in general. 2. Pathological ST segment changes: ST segment changes caused by acute myocardial infarction, acute pericarditis, myocarditis, etc. should be treated in time, and the ST segment may return to normal after the acute phase of the disease has passed. If ST segment changes are found, it is recommended to consult a doctor in time and ask the doctor to clarify the cause of the disease and guide the treatment.
