I have lone AF and have used several different medications, most with mixed results at best. Beta blockers were prescribed to me for borderline hypertension which runs in the family. They reduced my heart rate to that of bradycardia and I believe they had a role in my initial episode of AF. Later, a cardiologist put me on amiodarone and lanoxin and the episodes increased. I finally visited an EP who informed me that my type of AF was vagally-mediated and that virtually every taboo med combo had been given to me. He switched me to norpace (disopyramide) and I have not had an episode in over a year. Doctors are divided between rate control meds and rhythm control meds, although my EP thinks that maintaining NSR is the ticket if at all possible. I'm happy for all those who have had success with amiodarone, but the side effects are horrific. Anyone who has been advised to use it should think twice or at very least get a second opinion.
