Key result
The cardiac interbeat autocorrelation coefficient (rRR) strongly correlated with the LF/HF ratio (P<0.001) and EEG mean frequency (P<0.001) continuously during sleep.
Why the study?
Does the cardiac interbeat autocorrelation coefficient of R-R intervals (rRR) correlate with sympathovagal balance and sleep depth in healthy men?
Observational (n=15)
Does the cardiac interbeat autocorrelation coefficient of R-R intervals (rRR) correlate with sympathovagal balance and sleep depth in healthy men?
p-value: p=<0.001
The interbeat autocorrelation coefficient of R-R intervals (rRR) is a useful nonlinear tool for continuously evaluating sympathovagal balance and sleep depth.

May inform nocturnal HRV interpretation in sleep studies; leaves open validation for routine clinical use.
Otzenberger et al. (1998) conducted an observational in Healthy (n=15). Cardiac interbeat autocorrelation coefficient of R-R intervals (rRR) vs. Spectral power components and EEG mean frequency was evaluated on Correlation between overnight profiles of rRR and LF/HF ratio (p=<0.001). The cardiac interbeat autocorrelation coefficient (rRR) strongly correlated with the LF/HF ratio (P<0.001) and EEG mean frequency (P<0.001) continuously during sleep.
