From the 6 different doctors that I have spoken to, Afib becomes permanent over time after the AV node Ablation. I had the AV ablation 7 weeks ago.
Found out afterwords that the AV node can grow back.

My first 30 days were great. Had high energy, 80 bpm heart rate, and good blood pressure… under 140/90 even when in Afib. After 30 days I had a pacemaker check and when they tested the pacemaker leads I grew very very dizzy. Since then I’m in Afib multiple times per day and have to rest after walking a very short distance.

I’ve had 4 ablations over the course of 20 years. I’m 75 and
my heartbeat was from 145 to 165 for a week at a time. I had Afib for a few days and then a week or two without Afib.
I have hade a pacemaker for 20 years.

Please make sure that you know what your chances are of going into Afib permanently.,,
And how long you can expect before the Av Node grows back.

And any risks for Pulmonary hypertension and other conditions that could develop if you do go into Afib permanently…

GOOD LUCK with the procedure!
