Fig. 2From: Randomized comparison between dexmedetomidine–remifentanil and midazolam–fentanyl for deep sedation during catheter ablation of atrial fibrillationSubgroup analyses in different predefined sub-populations for the primary end point (a) and the incidence of hypotension (systolic blood pressure < 80 mmHg) (b). DEX: dexmedetomidine with remifentanil, MID: midazolam with fentanyl, ASA: American Society of Anesthesia, LVEF: left ventricular ejection fractionBack to article page
