I've just seen a private cardiologist in Sheffield. Told him that Bisoprolol does not agree with me, makes me very depressed, even suicidal. Cardiologist is steering me towards catheter ablation but I'm not keen and don't want to be bullied into this. I would prefer a pacemaker but my cardiologist says no. I'm in a quandary and getting to the point I just don't know what to do anymore. What happens if I just stop taking the bisoprolol?
