Thank you Muffin.
I have looked at the CAA website and they talk about the necessary course of action, i.e exercise tests etc when you have a 'Complete' right bundle branch block. My ECG states 'incomplete' which according to the internet is almost like a pre-am to a 'Complete' block. I have also read that providing the 'Incomplete' remains incomplete it shouldn't be of concern!
Fingers crossed for that then!
