As far as I know beta blockers can aggravate what is known as vagally mediated a-fib.
I had the most serious case of atrial fibrillation that my cardiologist has ever seen. He put me on 320 mg of sotalol which is a beta blocker and it stopped it. I did not want at age 46 to be on medications and I discovered a cure. What really settled my heart into a normal rhythm finally, and for good now the past 11 years, is strenuous EXERCISE. I joined a gym and a certified trainer gave me a program. After one month, slowly, bit by bit, with my cardiologist's okay, I was able to get off the beta blockers completely. And that was 11 years ago...and I am still walking on the treadmill several times per week.
Beta blockers may increase the incidence of atria fib with vagally mediated atrial fib. Otherwise, it is used to decrease heart rates with atrial fibrillation. Beta blockers do not decrease the incidence of atrial fibrillation. If you notice a strong correlation with beta blockers and atrial fib, calcium channel blockers might be a better choice.
Hope this helps.
I would say is it is very hard to tell. I have read anecdotes of vagal atrial fib increased with beta blockers. I have never read it in a text book. It would be difficult to prove.
so the beta blocker might have caused the afib after all is that what you are saying? Since prior to the beta blocker i never had this problem?
Thank you
i should also put on here that i have had an echo after my episode last year on christmas eve and i have also had an holter monitor and all came back normal
