Whenever we see a patient for fainting episodes (or syncope) which is actually quite common, the two big causes that need to be considered are cardiological (heart problem such as a leaky valve or rhythm problem) and neurological (seizures, strokes, etc...)  Your concern is understandable, but it sounds like your daughter's physicians have initiated the proper workup and I'm glad that the MRI was normal. The suggestion that she take in more salt and water is  to increase the amount of fluid in her vascular system which would theoretically increase venous return to her heart and subsequently provide adequate blood/oxygen to her brain (not to replace any electrolytes). In the meantime, you may want to discuss driving with your physician as the law differs from state to state. Finally, she may need more prolonged EKG monitoring. Good luck.

I am sorry to hear about your daughter, I know you must be terrified! If other tests turn out okay for your daughter, then a holter monitor should definately be tried. This is sort of like a portable continuous EKG box that will record her heart tracing. This is usually used for a 24 hour period, but should be used until it captures her rhythm during one of these events. It is possible that she could have a problem with the "wiring" so to speak, in her heart. If this is the case, there are medications or simple procedures which can cure this. I hope she has seen a pediatric cardiologist who will be able to tell you more about this. Best of luck to you and your daughter, let us know how it turns out.

The EKG has apparently ruled out epilepsy.  Have migraines been ruled out?  Your description of her episodes is somewhat consistent with migraine.  Does she consume aspartame (Equal, Nutrasweet,diet sodas, sugar-free foods), and if so, how frequently a day?
    Also, does she ever seem faint when she coughs or uses the toilet?
