Fig. 1 Effect of low-dose sotalol on the incidence of postoperative supraventricular tachyarrhythmias in the entire study population and on subgroups that underwent coronary artery bypass grafting (CABG) only or aortic valve replacement (AVR), with or without CABG. (af = atrial fibrillation.) The Annals of Thoracic Surgery 1997 64, 1113-1119DOI: (10.1016/S0003-4975(97)00804-7)
Fig. 2 Incidence and time of occurrence of the first episode of supraventricular tachyarrhythmias after operation. Note that there were two peaks: one around days 1 to 3 and one around days 6 to 7 postoperatively. Only 9% of the events occurred after day 9.
