Popis: | Heart rate variability was studied in 11 sleep apnea syndrome (SAS) patients. Two types of control groups were chosen; one group comprises patients having sleep disturbances other than SAS (SAS (−)) and the other group comprises patients who sleep normally (S(−)). Very low frequency (VLF) in frequency-domain analysis was significantly higher in the SAS group than in the control groups. Two parameters in time-domain analysis were significantly higher in the SAS group than in the S(−) group, but were not significantly higher in the SAS (−) group. The frequency component of VLF might serve as a screening method for SAS. Time-domain analyses were more ambiguous. |
