Does frequency-domain heart rate variability from 24-hour Holter monitoring accurately identify obstructive sleep apnea syndrome in patients with clinically suspected OSAS?
Frequency-domain analysis of heart rate variability from 24-hour Holter monitoring is a sensitive and inexpensive tool for mass screening of obstructive sleep apnea.
