My 9 year old had a screening EKG in order to be prescribed an ADD medication and the results were not normal. My son is adopted from Guatemala and I know nothing of his family's medical history or the nirth mother's behavior during pregnancy. The report indicated soemthing about possible ventircular problems and an emlargement or thieckening of the heart. I did not see the report, the neirologist who ordered the EKG read it to me over the phone. I am taking him to see a pediatric cardiologist next week,but in the meantime, I am wondering how much to worry. (My son appears healthy, is of average height and below average weight.)
