Hey there.
Listen, not to worry!
I'm 20. A couple of months later i was ready to go solo but couldn't until I'd nipped down to the docs to get my class2.
There was a huge delay on my medical issue as the ECG results came back saying i was clinically dead. Apparrently it's to do with the parameters to which the testing machine is set. It runs on a couple of very uniform lanes and if there's any sort of variable beat detected it goes mental. Anyway,long story short, i had to go for some extensive testing, which summarised in me being diagnosed as having Right Bundle Branch Block (RBBB). Sounds horrific but is merely a slight differ in the way your heart beats. With the extensive testing results logged on my CAA Medical History it will apparently save faffing around and money when it comes to getting my class1 in the next couple of weeks, as they will be able to dismiss the death signs the ECG machine will probably be chucking out.
Hope all goes well
