Atrial fibrillation (AF) is the most common arrhythmia. In 2010, more than 33.5 million people worldwide were estimated to be affected and the disease continues to increase in both prevalence and incidence (Chugh et al., 2014). Increased prevalence is due to both improved awareness of AF resulting in systematic diagnosis of AF being made earlier (Kirchhof, Breithardt, et al., 2016) and increases in the life expectancy of the general population (Hindricks et al., 2020).Age is a major risk factor for AF, along with other factors that can be modified by lifestyle changes, namely high blood pressure, high cholesterol levels, diabetes, obesity and obstructive sleep apnoea syndrome (Hindricks et al., 2020).
| BACKG ROU N DThe risk of AF for people of European descent and over the age of 55 is 1 in 3 (Hindricks et al., 2020). In Sweden, about 330,000 persons live with the diagnosis of AF (Riksförbundet HjärtLung, 2021).Since many individuals have asymptomatic AF and/or are undiagnosed, prevalence, in general, is assumed to be significantly higher (Kirchhof, Benussi, et al., 2016). Symptoms for those affected vary; some have no symptoms at all while others experience severe symptoms with a large symptom burden. Common symptoms are palpitations, shortness of breath and fatigue (Hindricks et al., 2020).Research shows that AF negatively affects health-related quality of life (HRQoL), often in relation to the severity of symptoms (Freeman
