Abstract :
Time-frequency analysis (TFA) is applied to the heart rate variability (HRV) signal for the purpose of observing the dynamical changes of spectral components. Smoothed-pseudo Wigner-Ville distribution (SPWVD) TFA was considered for processing the HRV signal. As a result, SPWVD TFA on HRV signals is shown to be a very effective method for analysing the power spectral density and for observing the time-varying components of HRV signals
