There are physiological or pathological reasons for ST change ECG, which need to be analyzed and diagnosed according to the specific situation.
1. Physiological reasons, often in emotional excitement, nervousness or after strenuous exercise will be ST ECG changes, there may be ST segment elevation or downward shift, this situation is generally not more than 0.1 mV, cardiac ultrasound, cardiac enzymes are normal, these are not to worry about, will not affect health.
2. Pathological reasons, for ST change ECG, if S-T segment elevation, accompanied by chest pain, chest tightness, precordial pressure, check the cardiac enzymes are elevated, this is often due to acute myocardial infarction. For the change of S-T segment depression with paroxysmal chest pain, chest tightness and panic, this condition is usually caused by coronary heart disease, angina pectoris, and insufficient blood supply to the myocardium.
In addition, hyperkalemia, hypokalemia, pericarditis, myocarditis can also appear ST electrocardiogram changes, which need to be determined by laboratory tests of blood electrolytes and cardiac ultrasound.
Therefore, the diagnosis of ST change ECG should be made according to the specific situation, combined with medical history, symptoms and related laboratory tests, cardiac ultrasound, etc., and then symptomatic treatment should be given.
