Hello, I was wondering if anyone could help? My 14 year old has been passing out and the consultant did an ecg which the cardiologist isn't happy with, apparently something called j waves ? My cardiologist said he needs to be seen soon but he only deals with adults, I phoned up to see how long the waiting lost is and appointment he won't be seen until December/January ! He needs an echo, 7 day ecg and table tilt test, in the mean time he has been told to do no exercises or sports, so I was wondering if anyone had experience of j waves or how I could get him seen sooner? Thank you.
