Heart rate variability (HRV) is a valuable clinical tool in diagnosing multiple diseases. This paper presents the results of a spectral HRV analysis conducted with 46 patients. HRV indices for the whole night show differences among patients with severe and mild apnea, and healthy subjects. These differences also appear when performing the analysis over 5-min intervals, regarding apneas being present or not in the intervals. Differences were also observed when analyzing the HRV nocturnal evolution. Results are consistent with the hypothesis that cardiovascular risk remains constant for OSA patients while it increases towards the end of the night for healthy subjects.
心率变异性（HRV）是诊断多种疾病的有价值的临床工具。本文介绍了对 46 名患者进行的频谱 HRV 分析的结果。整夜的 HRV 指标在严重和轻度呼吸暂停以及健康受试者之间存在差异。当在存在或不存在呼吸暂停的 5 分钟间隔内进行分析时，也会出现这些差异。在分析夜间 HRV 演变时也观察到了差异。结果与假设一致，即 OSA 患者的心血管风险保持不变，而健康受试者的风险则在夜间结束时增加。
