Apologies for starting a new post rather than continuing on the old one healthunlocked.com/afassoci...
but I wanted to add a photo and you can't do it as a reply.
A few people asked me to let them know how I got on so here it is. A week off 1.25mg of bisoprolol and energy is returning and dizziness decreasing. A few dodgy days at the start with an episode of AF and some fast palpitations but things have certainly settled. Hopefully it will continue. I have added below two graphs to show my heart rate before and after coming off the drugs. The before is a hectic day teaching and second a day spent doing a few easy odd jobs around the house and taking it easy. You can see how the betablockers hold the heart back - helps to explain the tiredness and dizziness.
