When my daughter was 11 she started experiencng palpatations and chest pain. No dizziness, SOB etc. The initial ECG they picked up a slight abnormality but further investigation by a pediatrition found nothing. They eventually discharged her as it righted itself. She is now thirteen and in the last 7 months this has returned but much more severe. Palpatations and severe chest pain, dizziness, SOB, headache and last night vomitting. She sometimes just gets the pain without palpatations. She is awaiting a appointment with a pediatric cardiologist, I took her to hospital last night. (usually we just ride it through as they never find anything) and they were very thorough. She had the chest pain for about 1/2 hour before I took her and it had subsided a little by the time we got there. ECG showed nothing, nor the blood tests, nor a chest x ray. (she has never had a ultrasound). The Dr said it may be panic attacks, but she is a very laid back kid, nothing fazes her, is not ever obviously anxious. She can wake in the night with these pains, or just taking a shower. I read up on panic attacks and she just does not fit the description. Every attack seems to be worse that the last. I have been advised to notify her school to call an ambulance when she has them as the have the ECG machine onboard and get her hooked up asap. Normally I just pick her up and bring her home and she is fine in a couple of hours.She discribes the pain as like a really bad cramp. The funny thing is her pulse is not racing. It is normal. Last night sitting around 50. Any input would be very much appreciated
