Why the study?
Does time-domain heart rate variability analysis accurately detect obstructive sleep apnea syndrome in patients with clinical suspicion?
Does time-domain heart rate variability analysis accurately detect obstructive sleep apnea syndrome in patients with clinical suspicion?
Time-domain HRV analysis, particularly the difference between daytime and nighttime SDNN index, provides an accurate and inexpensive screening tool for obstructive sleep apnea syndrome.
No takes yet. Share an insight, caveat, or question.
Time-domain HRV differences may aid OSAS screening in suspected cases; hypothesis-generating and requires prospective validation before practice change.
Roche et al. (1999) studied this question.
