From: Effectiveness of preoperative beta-blockade on intra-operative heart rate in vascular surgery cases conducted under regional or local anesthesia

Figure 2

Box-plots of heart rate at baseline and maximal heart rate during the pre-surgical incision period. Baseline values represent data collected upon entry to the operating room; bpm = beats per minute; boxes represent the 25th-75th percentiles; whiskers represent 5-95th percentiles. The β-blocker group experienced lower maximal heart rates compared to the non-β-blocker group (85 ± 22 bpm vs. 98 ± 36 bpm, respectively; p = 0.002).
