Figure 1 Percentage of patients developing postoperative atrial fibrillation. The numbers above the bars indicate the percentage in each group. There was a significant difference between NAP and RAP (p = 0.002) while the difference between NAP and LAP as well as between NAP and BAP did not reach statistical significance. Black bar = no pacing; hatched bars = pacing. BAP = biatrial pacing; LAP = left atrial pacing; NAP = no atrial pacing; RAP = right atrial pacing.
