Antiarrhythmic activity of befol in neurogenic atrial fibrillation is due to its cardiotropic and cholinolytic effects and coincides with the dynamics of the tonic component of vagal chronotropic influence. Unlike befol, sufan has no effect on the duration of atrial fibrillation despite a reduction of synchronizing component of the vagal chronotropic influence. Tonic component remains unchanged, which is probably responsible for the absence of antiarrhythmic activity of sufan.
