Heart rate variability (HRV) analysis, powered by computer science, measures autonomic nervous system influences on the heart. Altered HRV can predict disease outcomes and assess stress.

Area of Science:

  • Physiology
  • Biomedical Engineering
  • Computer Science

Background:

  • Heart rate variability (HRV) analysis has advanced significantly due to developments in computer science and digital signal processing.
  • Beat-to-beat heart rate fluctuations reflect the interplay of sympathetic and parasympathetic nervous system activity on the sinus node.
  • Numerous factors, including posture, respiration, age, gender, physical/mental load, pain, diseases, and drugs, influence HRV.

Purpose of the Study:

  • To provide a comprehensive overview of heart rate variability analysis.
  • To detail quantitative measurement methods for HRV.
  • To highlight the clinical potential of HRV in disease prediction and stress assessment.

Main Methods:

  • Quantitative measurement of HRV using time-domain methods.

  • Quantitative measurement of HRV using frequency-domain methods.
  • Discussion of the current limitations and underutilization of non-linear methods in clinical practice.

    • Main Results:

    • HRV analysis is a valuable tool for understanding autonomic nervous system function.
    • Time and frequency domain methods provide robust quantitative measures of HRV.
    • Altered HRV patterns are associated with various pathologies and physiological loads.

    Conclusions:

    • HRV analysis offers significant potential for predicting disease outcomes.
    • HRV can be utilized to assess physiological and psychological stress levels.
    • Further integration of advanced HRV analysis methods into clinical practice is warranted.
