Fig. 3From: Effects of nitroglycerin versus labetalol on peripheral perfusion during deliberate hypotension for sinus endoscopic surgery: a randomized, controlled, double-blinded trialHeart rate at time points between groups. Markers are means, error bars are standard deviations. Ext: extubation, PACU: post-anesthesia care unit. * denotes significance between both groups, † denotes significance compared to the baseline reading within nitroglycerin group, ‡ denotes significance compared to the baseline reading within labetalol groupBack to article page
