Figure 3. Postoperative changes in heart rate (HR) consistent with atrial fibrillation in a 72-year-old male. The top panel shows a highly abnormal breathing pattern marked by numerous apneic episodes (blue dashes). The bottom panel shows the HR (green) increase from the 60 beats per minute (bpm) range to 90 bpm for 5 minutes, and then an increase to a variable rate between 120 and 180 bpm. There are some associated changes in oxyhemoglobin saturation (red) consistent with hypoxemia secondary to apneic spells. EtCO2 – end-tidal carbon dioxide; RR – respiratory rate; SpO2 – oxyhemoglobin saturation; PR – pulse rate.
