The treatment of an abnormal T wave on the ECG, which is indicative of anterior wall myocardial ischemia, depends on what the patient’s current clinical symptoms are and whether other diseases have been diagnosed in the past. If the patient is a young woman with no specific discomfort and no previous diagnosis of other diseases, the first consideration is whether it is due to anemia or abnormal thyroid function. If it is due to these causes, it is necessary to correct the anemia or thyroid function so that this manifestation of myocardial ischemia can be improved. If an elderly patient has symptoms of precordial discomfort, chest tightness and chest pain, it may be due to coronary artery disease and angina pectoris, and the patient is advised to take oral medications such as aspirin, atorvastatin, isosorbide mononitrate and vancomycin, etc. If necessary, the patient is also advised to check coronary CT. However, if there is an abnormal T-wave with dynamic evolution, it is considered that an acute myocardial infarction may have occurred and requires emergency coronary intervention.
