Why the study?
Do nocturnal hypoxemia and pulse rate variability predict incident atrial fibrillation in patients investigated for obstructive sleep apnea?
Do nocturnal hypoxemia and pulse rate variability predict incident atrial fibrillation in patients investigated for obstructive sleep apnea?
Single-channel pulse oximetry can identify patients investigated for OSA who are at the greatest risk of developing incident atrial fibrillation based on nocturnal hypoxemia and pulse rate variability.
May support oximetry-based AF risk stratification in OSA; hypothesis-generating and requires prospective validation before practice change.
In patients investigated for OSA, nocturnal hypoxemia and PRV indices derived from single-channel pulse oximetry were independent predictors of AF incidence. Patients with both marked nocturnal hypoxemia and high PRV were at higher risk of AF. Oximetry may be used to identify patients with OSA at greatest risk of developing AF.
