Thank you for all your replies. It does help knowing most times it will be benign...still worry, but it helps. Her doctor did want to follow up with a specialist on the EKG which is why she said she'd get back to me. And we definitely will follow up with the cardiologist. Just to give a little more info, her dr last night said they rate them on a scale of 1-6, 6 being the loudest and hers was a 2-3. She said it was still heard when she laid down too.
Also I have a dumb question. Do you think if everything is just a minor issue and its benign, my DD would have any issues on roller coasters? Rock and roller coaster and expedition everest are her favorite rides and I'd hate to tell her she can't ride them anymore. Obviously I know this is not all that important and her health is a priority but I'm just curious. And with sports....good to hear that hopefully she can continue on with sports as well. Again, I know this is dependant on what is found, but I'm being optimistic that everything will turn out fine.
My kids are coaster warriors and have ridden everything Disney, Universal, Holiday World (Indiana) and Kings Island (Ohio) have to offer. I don't think you'll have an issue with that. I will admit, I was nervous about Mission Space Orange (due to the history of the ride) so I checked with their doctor before we rode. They got the go-ahead and all was fine.
Also have a question about the dentist. My mom said her friend has a condition as well where she has to take a prescription prior to the dentist. I'm just curious as to why? I guess I don't get the connection to the dentist and why its an issue?
Looks like others have answered this question. My kids have never needed this, but my sis did when she had a root canal.
Thanks again for all the replies. I'll update once I hear back from her doctor.
