Dear Mr Whirlybird
I was diagnosed with RBBB in the early 90s at the age of 35. I carried out a 24 hour ecg test etc etc with the CAA and have held a full unrestricted ATPL ever since. At each medical my doctor mentions the thing but it has never been of any consequence. I underatand that RBBB is a common symptom of having suffered a heart attack, however it can occur naturally and may be heriditary(as in my case). If this is the case it does not appear to be any problem whatever.
The only way you can resolve this is to contact the CAA and do whatever they say!! Good Luck.
