In December I had a second cardioversion for afib after being on amiodarone 400 for a month. I was in sinus rhythm for only 12 days (my first cardioversion, in Sept, without amiodarone, lasted only 3). I then took amiodarone for a month after the second cardioversion, 200 mg, but it didn’t help and I wanted off, happened today. Will have second ablation as soon as I am vaccinated. First ablation in 2017 lasted 3 years. Hopeful. Good luck. Ablation worked well for me, not at all painful, but is a hospital overnight.
