Thank you all
She has not had another ambulance ride and is taking medication to help strengthen her heart!
The doctor has authorized her to drive a car as long as it is local
Her quality of life is returning but she has realized that she needs to give up a few things like horseback riding.
Not all good news
They discovered some kind of defect that cannot be fixed that might kill her now or it might many years later. ( I don't know what it is called she gets wound up when I ask about it ).
