Background: Quality of life (QOL) is reduced in patients with atrial fibrillation (AF). However, data regarding the association between sleep quality, one of the major components of QOL, and AF are insufficient. This cross-sectional study aimed to elucidate whether sleep quality is reduced in patients with AF.
