I have a 16 year son who has autism, he had abnormal ekg but refuse to get further testing. he had a big outburst at the hospital snd became violent.

Family therapy: It is important for the parents to be involved closely in the therapy process when a child has autism. If he does have an abnormal ekg, eeg or other physical problems it is important to get followup testing to check out all posibilities. Your son needs to realize you are open to compromise about timing, situations of the test but he does not have the right to refuse.

He needs to see an: Adolescent psychiatrist or developmental/behavioral pediatrician for medications approved by his cardiologist to address his aggressive behaviors, which are probably anxiety-based. Our pediatric cardiologists do a short-term admission to use Ativan (lorazepam) or conscious sedation safely while obtaining an echocardiogram & all other further studies that are needed. His behavior can't preclude medical care.
