Hello doctor. This year, she is 25 years old and went to a health examination to perform an electrocardiogram and was diagnosed with myocardial ischemia. I went to the heart hospital to check again: electrocardiogram, blood test, strenuous jogging, echocardiogram, the results were said to be normal, but the only electrocardiogram still showed signs of myocardial ischemia.
So let me ask, can the electrocardiogram be affected by other factors, so there are signs of myocardial ischemia? Recently, I have been sad about love and family problems. I hope you can advise me, thank you doctor.

Hello Chau. I was examined by a cardiologist and it was found to be normal. The electrocardiogram showed myocardial ischemia, she had a stress electrocardiogram with normal results, ie, coronary artery disease was ruled out at the moment. You should see a cardiologist again if you have other unusual symptoms. (Remember to bring the test results you have done for your doctor's reference and comparison).
