ST segment elevation in the anterior interstitial wall is not necessarily acute myocardial infarction. Simple ST segment elevation in V1~V3 leads can be seen in acute myocardial infarction, early repolarization syndrome, acute pericarditis, etc. Acute myocardial infarction should be highly suspected when ST-segment elevation is bow-backed and upward on electrocardiogram, accompanied by chest pain, sweating and other symptoms, and the three markers of infarction are elevated.
The anterior interstitial wall is localized in leads V1~V3 on ECG. If the ST segment of ECG shows bow-back elevation, accompanied by pathological Q wave, T wave inversion and other changes, and the patient has symptoms such as chest tightness, oppressive chest pain, sweating, etc., and the three markers of infarction in the blood are elevated, then it is highly suspected that it is acute myocardial infarction, and it is necessary to carry out coronary arteriography as soon as possible, and interventional therapy is required if necessary.
In early repolarization syndrome, the electrocardiogram of ST segment shows bow-back downward elevation, which can include all the leads of V1~V3 and will never change, and most of the patients do not have obvious uncomfortable symptoms, which is usually seen in normal people; the electrocardiogram of patients with acute pericarditis can show a wide range of leads with bow-back downward elevation of the ST segment and depression of the PR segment, and the patients are accompanied by chest pain and dyspnea.
If the patient’s electrocardiogram suggests ST segment elevation in leads V1~V3, it is necessary to distinguish whether the ST segment is bow-backed upward or downward, and it is recommended to go to the hospital in a timely manner to find out the cause of the ST segment elevation with the combination of medical history, symptoms, signs and symptoms, and cardiac ultrasound and other examinations, and then take active treatment.
