This study introduces a real-time filtering algorithm to improve the accuracy of spectral analysis of heart rate variability (HRV) by correcting erroneous R-R intervals. The method effectively filters noise, enhancing autonomic nervous system (ANS) activity monitoring during medical procedures.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Physiology

Background:

  • Spectral analysis of heart rate variability (HRV) is a non-invasive method to assess autonomic nervous system (ANS) activity.
  • Continuous HRV analysis is crucial for monitoring ANS during medical procedures, but ECG signal noise complicates its reliability.
  • Signal perturbations lead to erroneous R-R intervals, compromising the accuracy of HRV spectral analysis.

Purpose of the Study:

  • To develop and evaluate a real-time filtering algorithm for R-R interval series.
  • To improve the reliability of continuous spectral analysis of HRV by addressing signal noise.
  • To enable accurate tracking of ANS activity and transient events during medical procedures.

Main Methods:

  • A real-time filtering algorithm was designed to process R-R interval series.

  • The algorithm detects disturbed R-R interval samples caused by ECG signal perturbations.
  • Erroneous samples are replaced with the most probable values, preserving real recording time.

    • Main Results:

    • The filtering algorithm successfully detects and replaces up to 90% of erroneous R-R interval samples.
    • The method maintains the real recording time of the R-R interval series.
    • The filtering process demonstrated no significant adverse effects on the results of frequency analysis.

    Conclusions:

    • The developed real-time filtering algorithm significantly enhances the accuracy of spectral HRV analysis.
    • This technique provides a reliable method for continuous ANS activity monitoring, even with noisy ECG signals.
    • The algorithm facilitates improved tracking of physiological events during medical interventions.
