My 14 year old daughter keeps passing out. She gets dizzy, clammy, starts sweating profusely and then she says everything turns black. This all happens when she exerts herself like in gym class. Her gym teacher says that she becomes unresponsive and her pupils get very dilated. She s had a holter monitor, ekg, stress test, and an echocardiogram and they all are normal. What do I do now?
This sounds very much like a syncope. Most of the workup has already been done. I would recommend adding a tilt-table test, a doppler-sonogram of the cerebral arteries and to check the glucose by finger stick measurement after a spill occurred. There are several questions a doctor can ask to ascertain himself that this cant be a seizure (I guess this was the case), in doubt an MRI and EEG should be performed.
