This study compared the efficacy of flecainide versus pilsicainide in reducing the frequency of AF and improving quality of life (QOL) in symptomatic paroxysmal AF patients without structural heart disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The Atrial Fibrillation and Quality Of Life (AF\u2010QOL) study was a prospective, multicenter, randomized, open\u2010label crossover study that compared flecainide and pilsicainide as antiarrhythmic drug therapy. Patients were randomized to receive 3 months of treatment with flecainide twice daily or pilsicainide 3 times daily. Each treatment consisted of a dose\u2010finding phase (weeks 1\u20134) and an efficacy phase (weeks 5\u201312). Forty\u2010three patients completed the trial. The main outcome was the number of days with documented AF episodes using a patient\u2010operated electrocardiogram. QOL questionnaires (SF\u201036 and AF\u2010specific QOL scores) were also completed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The median (range) AF frequencies (days\/8 weeks) were 2 (0\u201350) in the flecainide treatment group and 1 (0\u201354) in the pilsicainide treatment group (no significant between\u2010group difference). No significant difference in the first recurrence of AF during the efficacy phase was noted between flecainide and pilsicainide treatments. The frequency and severity scores of AF\u2010related symptoms improved from baseline to the end of the treatment periods.
