My GP told me that I would probably need both done very soon after my initial diagnosis. Wondering if this is because I have not been able to tolerate either of the drugs tried so far which were Bisoporal and Slozem. From the posts I have read it seems to be that post Ablation a Beta blocker is needed for at least a short period. I do have Bisoporal to take as needed and that does seem to work. Taking 2.5mgs every day caused light headedness with a pulse of 42. The lower dose did nothing to alleviate the AF. Slozem exacerbated my hot flushes and I had headaches and burning facial redness. I have seen a cardiologist who has now referred me to an EP. I also have a chronic lung condition, COPD which limits the use of some medications.Thanks for any advice. Previous posts and the AF association leaflets have answered all my other queries which has been a great help. Thanks.
