Words and terminology are indeed important. I had to renew my driver's license two years ago. I was required to fill out a form which included a question about medical conditions. I stated, frankly, that I have atrial fibrillation, but that it is under control via a catheter ablation (meaning I don't currently experience any ectopy or fibrillation). The clerk immediately reached under her counter space and flipped a doctor's assessment form for me to get my family doctor to fill out and send on to the Insurance Corporation of BC, the monopoly state insurance agency. I declared emphatically that I am not fibrillating due to a successful ablation, but she said I still have to have a competent authority declare that my condition is not a danger to the public. I got my license renewed, but not until they received the form in Victoria.
