Abstract Introduction Restless sleep disorder (RSD) has been recently characterized clinically and polysomnographically in children and differentiated from restless legs syndrome (RLS). Heart rate variability (HRV) is a reliable method to quantify autonomic changes during sleep. The aim of this study was to characterize HRV in children with RSD, RLS and normal controls, with the hypothesis that children with RSD have a shift toward sympathetic predominance during sleep. Methods Polysomnographic recordings from thirty-two children who fulfilled RSD diagnostic criteria (19 boys and 13 girls), 32 children with RLS (20 boys and 12 girls) and 33 controls (17 boys and 16 girls) were included. Four ECG epochs were chosen, one for each stage, and were analyzed for automatic detection of R waves. Time domain and frequency domain HRV parameters were obtained and analyzed. Results Age and gender were not statistically different between groups. In terms of time domain only the standard deviation of the average RR interval during stage N3 was slightly but significantly higher in RSD than in RLS patients. In terms of frequency domains, the LF band and the LF/HF ratio were increased in RSD and the HF percentage was lower in RSD during sleep stages N3 and R. The LF band and the LF/HF ratio increased in RLS and the HF percentage was lower in RLS during stage W. Conclusion Children with RSD have increased sympathetic activation during sleep, particularly N3 and REM, compared to controls but, as expected, not during wakefulness. Differently, children with RLS have sympathetic activation during relaxed wakefulness preceding sleep and during sleep.

Alterations in the autonomic cardiovascular control have been implicated to play an important etiologic role in preeclampsia. The present study was designed to evaluate autonomic functions in preeclamptic pregnant women and compare the values with normotensive pregnant and healthy nonpregnant controls. Assessment of autonomic functions was done by cardiovascular reflex tests and by analysis of heart rate variability (HRV). Cardiovascular reflex tests included deep breathing test (DBT) and lying to standing test (LST). HRV was analyzed in both time and frequency domain for quantifying the tone of autonomic nervous system to the heart. The time domain measures included standard deviation of normal R-R intervals (SDNN) and square root of mean squared differences of successive R-R intervals (RMSSD). In the frequency domain we measured total power (TP), high frequency (HF) power, low frequency (LF) power, and LF/HF ratio. Cardiovascular reflex tests showed a significant parasympathetic deficit in preeclamptic women. Among parameters of HRV, preeclamptic group had lower values of SDNN, RMSSD, TP, HF, and LF (ms2) and higher value of LF in normalised units along with high LF/HF ratio compared to normotensive pregnant and nonpregnant controls. Furthermore, normotensive pregnant women had lower values of SDNN, TP, and LF component in both absolute power and normalised units compared to nonpregnant females. The results confirm that normal pregnancy is associated with autonomic disturbances which get exaggerated in the state of preeclampsia.
