This review explores heart rate variability (HRV) methods and applications. It covers autonomic nervous system influences and clinical uses like coronary heart disease and heart failure.

Area of Science:

  • Physiology
  • Cardiology
  • Biomedical Engineering

Context:

  • Understanding cardiac autonomic function is crucial for diagnosing and managing cardiovascular diseases.
  • Heart rate variability (HRV) analysis offers insights into the complex interplay between the heart and the nervous system.
  • Current research focuses on refining HRV assessment methods and expanding its clinical utility.

Purpose:

  • To provide a comprehensive overview of current heart rate variability (HRV) assessment techniques.
  • To explore the physiological basis of HRV, including cardiac automaticity and autonomic nervous system modulation.
  • To discuss the diverse clinical applications of HRV, with a focus on cardiovascular conditions and neuropathy.

Summary:

  • This work reviews the mechanisms, evaluation methods (time-domain and frequency-domain), and clinical applications of heart rate variability (HRV).
