I had paroxysmal Afib. My cardiologist put me on Amiodarone. That did stop the Afib but also put me into bradycardia. My heart rate was in the 30's, and I passed out. I then received a pacemaker which has controlled my heart rate well. However, after 1 1/2 years with the pacemaker, I went into Afib. I spontaneously converted after a month. A year later I was in persistent Afib for 3 months. I had a cardioversion and am now on Flecainide daily to (hopefully) prevent another episode. Your electrophysiologist will determine the best course of action for you. I resisted the cardioversion because I know so many people for whom it did not work. However, it has been 5 months since I had it, and I have not had another episode. If your pacemaker is monitored, your electrophysiologist knows when you are in Afib. They called me both times I went into Afib after my pacemaker. As gloaming said, you may need a catheter ablation. I was surprised when I went into Afib the first time because I thought the pacemaker would prevent that happening. Obviously, it does not. Good luck!
