My daughter, who is 11, had some blood work and an Ekg done recently because of some migraines and a fainting episode. The Ekg came back showing possible heart enlargement. I'm waiting around for the doctors office to get her an appointment with a cardiologist. In the meantime, I am extremely worried. The doctor tried to tell me, because I was very upset, that EKG's are not very accurate at detecting heart enlargement in children, and that it was like a 99% chance that it was off/misleading... I'm just still very worried. Any experiences with false reading on ekg?
