atrial fibrillation
"5 episodes of paroxysmal atrial fibrillation in 3 years all resolved with iv flecainide in A&E. 6 more episodes in last last year all resolved within 3 hours at home by taking  pill in pocket (i.e. 200 mg flecainide). Can't work out consistent trigger factor so avoid all known ones. Background treatment for hypertension with ramipril and beta blockers for rate control, but otherwise very fit and healthy 63 year old woman. Brilliant to be able to treat without hospital admission."
