Area of Science:

  • Physiology
  • Complex Systems Science
  • Biomedical Engineering

Background:

  • Heart rate exhibits complex oscillations and long-term variability, often characterized as 1/f noise.
  • Understanding the physiological control mechanisms of heart rate is crucial for interpreting its variability.
  • Heart rate variability (HRV) patterns differ significantly between healthy individuals and those with various medical conditions.

Purpose of the Study:

  • To review the physiological control of heart rate.
  • To describe typical patterns of heart rate variability (HRV) observed in both health and sickness.
  • To briefly consider potential dynamical mechanisms underlying HRV.

Main Methods:

  • Literature review of physiological control of heart rate.
  • Descriptive analysis of established HRV patterns in health and disease.
  • Conceptual exploration of dynamical systems theories applied to HRV.

Main Results:

  • Heart rate variability is influenced by multiple physiological regulatory systems.
  • Distinct HRV patterns are associated with specific health states and pathologies.
  • 1/f noise is a common characteristic of long-term heart rate variability.

Conclusions:

  • Heart rate variability is a complex physiological phenomenon reflecting integrated control mechanisms.
  • Analysis of HRV patterns provides insights into cardiovascular health and disease states.
  • Further research into dynamical mechanisms could elucidate HRV generation.
