Boxplots showing microcirculatory parameters. These parameters were obtained by NIRS in combination with a vascular occlusion test during postoperative atrial fibrillation (POAF) and during incremental esmolol dose regimen (25 μg/kg/min (E25), 50 μg/kg/min (E50), 100 μg/kg/min (E100), and 200 μg/kg/min (E200)). Continuous variables were analyzed with a linear mixed-effects model. a Tissue oxygen saturation (StO 2 ), (b) resaturation speed, (c) desaturation speed, and (d) variation in StO2 during reperfusion (DeltaStO 2 )
