Please don't think this can only be a "birth defect" as the previous poster stated. Be sure to have your son tested for Hypotrophic Cardiomyopathy. It's a simple Echo that could save his life. Please go to www.hcma.org for more information and a listing of doctors in your area who specialize in this. Hopefully, it is nothing more than a mild heart murmur that he may possibly grow out of.
It is very important to go to a cardiologists who understands this disease as most cardiologists will never have a patient with HCM.
