<s>[INST] My 16 year old daughter has been suffering from a severe eating disorder for 4 years. She just had an abnormal EKG. It showed incomplete rt. bundle block pattern and her labs show low ALT at 10 and low alkaline phos. at 106. We are trying to get her into a residential eating disorder hospital. I am reading that she could have already had a heart attack. She is scheduled for an echo but it isn t for 11 days. I am worried that she isn t gonna live to get the treatment she needs [/INST] Normal levels of ALT range from about 7-56 IU/L. Normal levels of ALP ranges from 44 to 147 IU/L. In your child values of both ALP and ALT are within NORMAL range. Right bundle branch block (RBBB) in child Chat Doctor.  To find out the exact CAUSE of RBBB your doctor has advised Echocardiography. I don't think this problem has anything to do with eating disorder from which your child is suffering. Isolated RBBB is not fatal. It is usually considered benign condition. So you need not worry so much. After Echocardiography your doctor will determine the cause of RBBB and will treat accordingly. </s>
