Hello! I have had a-fib for at least 10 years off and on. I had an ablation in 2013 which proved unsuccessful. I'll make a long story short: Over the past three years, my a-fib became active 24/7. My cardio team at Mayo has worked tirelessly to help me with it. I met with two Electro-Physiologists in Cardiology this February. I spent three days in St. Mary's in Rochester under observation while they prescribed a medication. It worked. I am in normal sinus rhythm. I am not at liberty to tell you the name of the med except to tell you it is expensive and Blue Cross will not pay for it. I'll let your cardio team proceed with the process as it might not be what it indicated for you. All I can say is, I am a happy camper and I can tell the difference. All the best to you.
