[|Human|] my son is 13 years old, he has coloboma. For the past year or so he has complained of chest pain after running. He has had chest x-rays and an EKG and they showed nothing wrong, he has not been diagnosed with asma.. Would a stress test show if there was something the x-rays can t see?
[|AI|]  Coloboma sometimes accompanies what is called CHARGE syn Chat Doctor. ECG can role out the electrical and functional abnormalities of the heart, but it doesn't show defects or structural abnormality .so an echocardiogram is the gold standard method to diagnose these defects which some times can present with chest pain or exercise intolerance. I highly recommend doing ECHO to this young man , and I hope he doesn't have any defects and this pain is a musculoskeletal pain.
