Pulse-rate variability during sleep studies predicts stroke risk in patients with obstructive sleep apnea

Conclusion: In patients investigated for clinical suspicion of OSA, PRV derived from oximetry during sleep studies allows a reliable prediction of stroke incidence: patients with marked low sympathetic/parasympathetic tone, expressed as a decrease in the LF/HF ratio, were at higher risk of stroke.
