I got AF while training (football) 2 years ago. It didn't go away by it self I had to use a defibrillator to convert back to sinus rhythm.. Since I was young and it was a first time event the agency put an OML (valid as or with qualified co-pilot) limitation in my medical for 6 months until I was able to show them that I was fit for flight.. Within these 6 months I did 2 ultrasounds, 2 stress tests, 2 48-hour ECG monitoring and normal ECGs, all tests showed no evidence of AF so I got my unrestricted MED-1 back! I assume that if I get it again it will be very difficult to maintain an unrestricted MED or maybe it will be a complete loss of MED-1.. Ι strongly suggest everyone with a similar condition to consider loss of MED-1 insurance.. I will certainly do it.. when I find a job ...
