My 7-year-old son had an EKG one year ago to check for rheumatic fever (as a cause for a chronic movement disorder). EKG showed possible RVH, with suggestion to repeat EKG in one year. Repeat EKG showed RVH. Not much info available on RVH. It seems to be a symptom of a larger problem, such as pulmonary stenosis, pulmonary hypertension, or tetralogy of Fallot (isn't this always diagnosed as an infant, and wouldn't I see other signs if this was the case?). I understand RVH is very rare. He is scheduled for an echo and chest x-ray. If RVH is confirmed, what other tests will be required to determine the cause? I am unable to find a treatment anywhere. Is there one? Will he have any restrictions placed on him? What are the long and short-term implications of this? Although we have significant heart disease in my family (always past age 60), we have no family history of pediatric cardiac problems. Thank you so much for taking the time to answer my questions!
