Good news!!!! ish?
Great in fact, the flat T wave was not apparent in either a normal or exercise ECG done by my consultant.
Basically, he thinks the leads on my first ECG may have been slightly misplaced giving an incorrect reading. He could find no way of replicating the readings. He did find an anomally (spelling?) in one of the waves (different to the first one!) but it was unaffected by the exercise test and therefore he was satisfied that combined with my age and general fitness it has probably been present since birth and is of no consequence.
So my class 1 is retained. Wohoooooooo.
Thanks to all for the advice support and help.
One of the best things about Pprune is just such support.
