摘要: Heart rate variability (HRV) is a valuable clinical tool in diagnosing multiple diseases. This paper presents the results of spectral HRV analysis conducted with 46 patients. indices for whole night show differences among patients severe and mild apnea, healthy subjects. These also appear when performing over 5-min intervals, regarding apneas being present or not intervals. Differences were observed analyzing nocturnal evolution. Results are consistent hypothesis that cardiovascular risk remains constant OSA while it increases towards end
