Thanks Gardener.
Thanks for your advice. It makes me feel more at ease as I am worrying about it. In my case a small section of my ECG showed T Wave Inversion. I also spoke to an ex RAF pilot who was also getting his medical, and he said that this gets pulled up a lot of times and its very rare for someone to be denied a medical because of it. My understanding is that should it pop up again at later ECG's it can be dismissed.
Did you have to book in an appointment when you had to go back to the CAA, and did you have to pay for it?
Regards,
