In a nutshell I have just been to the AOSB Main Board medical today in which I got an ECG scan which flagged up a problem which prevents me from joining the army, but a problem which would not cause a pratical block to training more a case of the MOD ticking boxes. It depends on: 1. If the RN officer medical includes an ECG scan and 2. If the Army and Navy exchange medical info for prospective applicants
I'm thinking that there would be plenty of serving personnel with lots of medical problems, that have not been spotted, by the Docs or divulged by the person,who was aware!! That would, have debarred them from entry..I know that for a fact !!!!!!!!!!!!
Happened to me.
Had symptoms of epilepsy but never realised till later life.
All came to a head later during my career in the mob. When I had a full seizure.
MOD decided I was unfit for further sea service.
Don't understand it. I spent most of my naval career falling over.
An ECG isn't part of the medical, but as you mention it, I suspect you have a reason to worry about having one. If you want to be aircrew you will have one taken later in the process.
If you have or think you have a problem, good advice is to tell the Dr, be honest.
