This study separates heart rate variability (HRV) signals into fractal and non-fractal components using wavelet transform. This method enhances the analysis of HRV signal characteristics, particularly the fractal component.

Area of Science:

  • Cardiology
  • Signal Processing
  • Biophysics

Context:

  • Heart rate variability (HRV) analysis is crucial for understanding cardiac autonomic function.
  • Traditional HRV analysis methods may not fully capture complex signal dynamics.

Purpose:

  • To develop a novel method for decomposing HRV signals.
  • To differentiate between fractal and non-fractal components within HRV signals.

Summary:

  • Wavelet transform was employed to divide HRV signals into distinct 1/f fractal and 1/f non-fractal components.
  • This decomposition facilitates a more nuanced understanding of HRV signal properties.

Impact:

  • Enables improved quantitative analysis of the fractal characteristics of HRV signals.
