    Hi . I also took bisop for a fast H.rate for 4 years. I had awful side effects but was fobbed off by several docs. Eventually another doc changed it to atenolol and gradually increased the dose to 100 mgs. I had lots of side effects and then persuaded my doc to lower it to 50. I read all sorts of info on the web and decided to ask a new GP if I could lower it to 25, I have done so and after a month the withdrawal effects were very frightening. I put up with these and have decided to cut the dose again. I'm now on about 8-10 mgs. My heart rate is no worse than before either on biso 10 mg,or 100 atenolol! Side effects have almost disappeared. I can now walk...not feeling as though I was walking in treacle, no ringing in my ear, my vision has improved so much I will need new glasses, no afternoon sleep needed and my head and brain can now think and function!

    ok,I don't know if I'm doing harm to my heart..I have A/f, but my blood pressure is good and my pulse still fluctuate and can reach 114 b.p.m.

       I've read that generally if you have side effects from one beta blocker,then it's likely to have the same effect. up about it's's not the one to be chosen as first choice....But....who knows? Such a difficult one and I'm no doctor! 

     I hope you are ok . I think the atenolol stays in the body for 7/8 hours if I remember rightly. Probably why I used to feel so much better when it was time relax in the evening and go to bed! Hope this helps.
