2 1/2 years following second ablation and getting random ectopic runs and short bursts of Tachycardia weeks apart. Stopped taking Bisoprolol 10 months ago since it had no effect on the frequency of events. Consultant has put me on a small dose of Nebivolol and 8 weeks in I am really beginning to notice some side effects. These include, difficulty in sleeping, vision issues (difficult to describe but minor focusing and a goldfish bowl effect at night) and slight swelling of the ankles in the evening. I have a resting pulse of 50 now as opposed to about 64. Fingers crossed, no ectopics or tachycardia so far. Just wondered whether anybody else has taken this drug and their thoughts.
