Comparison of log PB% and log AHI from the CPAP devices: paroxysmal Af group vs. persistent Af group vs. permanent Af group. Average PB%Device, 0.69 vs. 2.37 vs. 6.81, respectively. Log PB%Device was significantly higher in the persistent Af group and permanent Af group than in the paroxysmal Af group (p = 0.032, p < 0.001). Average AHI, 4.01 vs. 5.56 vs. 7.66, respectively. Log AHI was significantly higher in the persistent Af group than in the paroxysmal Af group (p = 0.002). *p ≤ 0.05, one-way ANOVA followed by Tukey’s post hoc test. PB, periodic breathing; AHI, apnea/hypopnea index
