Fig. 1From: Randomized comparison between dexmedetomidine–remifentanil and midazolam–fentanyl for deep sedation during catheter ablation of atrial fibrillationChanges in the mean SBP and DBP (a), heart rate (b), and peripheral oxygen saturation (c) during radiofrequency catheter ablation for atrial fibrillation in the two groups. *p < 0.05 between the two groups at the time point. SBP: systolic blood pressure, DBP: diastolic blood pressure, DEX: dexmedetomidine + remifentanil, MID: midazolam + fentanylBack to article page
