Thank you so much to everyone that posted their thoughts and invaluable advice. I saw my cardiologist on Monday and discussed the Bisopropol side effects. His take on things was that we now had a diagnosis and were treating the rhythm which is all that needed to be done at this stage. He prescribed Carvedilol and said to go back if I didn't get on with them. As my heart rate is generally in the low 50's, I foresee the same issues. I asked him if I could give up medication for 3 months and really go for it with lifestyle changes, and he agreed as I have so few issues at present. As for the referral to an EP, he said the time to consider that was when I got to the stage of needing cardioversion. He is clearly not a fan of ablation! It's bad enough having AF without having to fight the experts!
Thank you all once again, and I'm not giving up! 😁
