Also the enlarged heart concerned me. I know you said she had an echo, but has any other studies been done such as stress test? Toprol in and of itself can cause syncope episodes cause someimes it will cause the heart rate to go too low <60.
Toprol is a rough drug for adults, let alone a child.

Has congenital cardiomyopathy been ruled out? This disease is diagnosed frequently in teens playing sports cause often they will faint on the sports field.
I think you mentioned her kidney function is ok.
I would take my child to the Cleveland clinic in a heartbeat.
