Like you, I had a cardioversion procedure which took me out of AFib with one shock. Although I had resisted it, I was happy with how easy and quick it was. Actually, I had THREE cardioversions (all quick and easy with 1 shock)! After the first, I was out of AFib for 7 months and feeling great. After the second, I was out of AFib for 2 months. The third was just 2 weeks ago. My EP said I can't have my heart shocked every few months (although many people do). He strongly recommended an ablation because cardioversion is generally a short-term fix. Hope yours lasts a long time!
