My son is interested in USMMA and USCGA. He is entering Junior year in HS so we are early in the process. While nothing has been diagnosed to date, he on rare occasions gets periods of rapid heartbeat during intense athletics. He is fit in all oher aspects and incidence of it is declining as he has gotten older (now 16). He had a checkup today and is going to visit a cardiologist. Perhaps a heart murmur but too soon to tell. His pediatrician has been aware of it and did not highlight it as a matter of undue concern, but of course not in the context of admission to one of the academies. Assuming it is diagnosed as for argement's sake, a mild heart condition, are waivers for something like that ever granted? Thanks much for any help.
