  Spectral Analysis of Heart Rate Variability Signals using Stockwell-Transform

  By Ram Sevak

  Abstract: This paper introduces the use of Stockwell transform (ST) for spectral analysis of heart rate variability (HRV) signals in time-frequency domain. The ST is depicted numerically and compared with well-liked method of wavelet transform known as continuous Morlet wavelet transform (CMWT). The results of this study show that the normalized mean power and total normalized power in VLF (0.004–0.04 Hz), LF (0.04–0.15 Hz) and HF (0.15–0.4 Hz) were improved compared …
