Fig. 3From: Effect of flecainide on atrial fibrillatory rate in a large animal model with induced atrial fibrillationAFR in horses with spontaneous persistent AF. Data are presented as 10-min average. a illustrates a stable AFR without drug intervention (n = 3) and b illustrates the attempt to terminate AF with flecainide (injection time = 0, n = 1). Note the significant decrease in AFR after flecainide infusion, followed by an increase as the flecainide failed to restore sinus rhythmBack to article page
