Can I travel to Tibet if my electrocardiogram changes in the ST segment?

There are many kinds of ST segment changes

If it is Gongbei elevation, it indicates myocardial infarction, and you must rest and be hospitalized

If it is ST segment depression, it indicates myocardial infarction. Ischemia and depression can be divided into mild, moderate, etc. The specifics must be consulted by the doctor. If necessary, further tests such as exercise stress test, cardiac color Doppler ultrasound, etc., and regular electrocardiogram review
