I have been on Amiodarone for a year and half. I had 2 ablations and got a pacemaker because they didn’t work . That worked for 5 years and then the A-fib came roaring back. I was having it 50% of the time. My dr said if I was 50 he wouldn’t give it to me. Since I have been taking it the A-fib is less then 1 %.
