To assess the variability of heart rate in the frequency domain, usually the spectral density function of the tachogram …, robustness is an issue. Therefore, the heart rate variability is assessed by robustly estimating the spectral density function of …, and therefore provides fully automated signal processing which will facilitate reliable and reproducible heart rate …
