For me it was similar in the fact that I was told an echocardiogram was required as there were signs of x axis deviation (if memory serves me correctly, initial was 1999). At the time I remember getting home and doing a search for x axis deviation and reading a few threads thinking I only had a few days left! Having already booked to fly to Florida to start my training I only had two or three weeks to get everything sorted out. I was fairly fortunate and after explaining the situatuion to my doctor I was quickly referred to a cardiologist at my local hospital...cost me a box of coffee but I was again lucky he was ex RAF so very understanding and said I do not know why you need this doing as it is fairly common! Anyway report and echo sent back to CAA then invited to see a doctor at the CAA for a fee who "signed me off" as fit.
