7 year old daughter with 2 passing out spells over the past year. Family Dr. Says EKG show normal activity and we shouldn't worry unless it happens again. Is this good enough? She has been a Healthy child over all and these spells only lasted several seconds and were about 9 months apart.
A normal EKG ruled out arrhythmia as a cause of her fainting episodes. However, there are other causes of syncope (passing out) that are serious and should be considered.
For example, if she passed out while playing sports/exercising, then she must have an echocardiogram to rule out structural heart disease. A disorder called hypertrophic cardio sympathy can cause symptoms of syncope. It is a rare disorder, but can lead to premature death if untreated.
If her syncope episodes are related to posture (e.g. standing up from a sitting position) then anemia should be ruled out. This type of syncope is called orthostatic hypotension. It is a sign of anemia or low blood pressure.
Seizures can cause loss of consciousness, but generally last longer than seconds, and are associated with arm/leg movements.
If she passed out while playing sports, get a referral to see a pediatric cardiologist right the way.
I have some additional input here; syncope or fainting can also be due to neurological issues. I think the pediatric cardiologist is a good idea, even if she did NOT pass out during sports. An EKG only takes a short picture. Holster monitors are worn over longer durations. 24-48 hours, and they can get a better idea of the hearts rhythm than a 30 second EKG.If this continues I also suggest a pediatric neurologist. Not all seizures are associated with arm or leg movements; absence seizures can look to the untrained eye like a blank stare or eyes rolled upwards.
