I have no other heart problems. Have been taking cardizem 240mg for 2 month. , without a-fib until I got the flu seems fever brings on a-fib
Many patients may go back to atrial fibrillation even while taking their medications.
You are best to talk to your heart specialist as other options may need to be considered.

Everyone is different but I feel that Cardizem caused more palpitations which then led to A Fib for 24 hours. However, cardizem intravenous was the only thing to bring me to normal sinus rhythm in ER, go figure. So I am back on Atenolol 50 mg a day for blood pressure and Flecinide 50mg a day. I only had some fatigue at first with the Flecinide Now my Dr wants to increase the dose to 50 mg twice a day and I am scared. I had no incidents since January 2011. This month 2 episodes, one 11 hrs one 4 hrs. BUT I am in a new job (Pharmacy Tech) and on my feet 7 hrs a day. That would kill a young person! I am 69.
