I had my third ablation on February 9 . I have had 6 episodes of a fib since, lasting only 2 days each. My heart rate has been 120 to 130 each time so I did not have to go onto the hospital. There is a so called " blanking period " of 3 months or so where the heart is healing so a fib can and might come back. Medication might help. I am back to exercising now and feel that it is probably healed now.
Take care....
