Some patients' symptoms may genuinely be side-effects due to the beta-blocker tablets, but, in reality, many of the symptoms which may lead to people stopping beta-blockers are actually experienced at similar rates compared to placebo. The symptoms may be caused by heart failure itself, or the expectation that they will have a side effect when they take a tablet (the nocebo effect). There is a need to be able to identify the majority of patients who aren't actually having side-effects so that they can restart beta-blockers and not miss out on life-prolonging treatment. To answer this question reliably and with high precision requires a personalised approach with an 'N-of-1' study. This study will measure participants' symptoms in three scenarios: taking a beta-blocker tablet (bisoprolol 2.5mg) or a placebo tablet or no study medication in a randomised order. The primary aim of this study is to determine, for an individual, whether the adverse effects of beta-blockade in heart failure are genuine. Specifically, the objectives are: 1.
