A technique based on the Hilbert-Huang transform is considered with a view to improving the heart rate variability assessment. RR intervals of circadian rhythm pre-processed by the interpolation and resampling method are investigated. Empirical modes in heart rate are detected with the help of successive operations. These modes have shown that there is an additional modulatory effect on heart rate.
