Heart Murmur :(

[TheMercenary]

Sounds like she needs an Echo at least, an EKG, and given that she is already an athelete I would not worry much. Now if she was suddenly not performing as she had in the past, was more tired than usual or had symptoms during exercise that would be worse. No need to worry about something that you don't have any information about. Many people have murmurs, they are asymptomatic, they exercise, and it changes nothing in their life. The biggest thing that happens is they fall into a group of people who need antibiotics with dental work or invasive procedures, but that is about it. Please don't worry at this point but I would recommend you see a peds cardiologist to remove all your fears.
