Measurement of Heart Rate Variability

Western Journal of Nursing Research, 1995
Heart rate variability (HRV) is a measure of autonomic nervous system balance/imbalance. Measurement and analysis of HRV can be classified into time domain analysis and frequency domain analysis. lime domain analysis is a general measure of autonomic nervous system balance and is based on altered versions of the measurement of the standard deviation ...

Heart rate and heart rate variability, a pharmacological target

Cardiovascular Drugs and Therapy, 1997
Heart rate varies with respiration, blood pressure, emotion, etc., and heart rate variability (HRV) is presently one of the best indices to predict fatal issues in cardiac failure and after myocardial infarction. HRV depends on various reflexes. In addition, parallel studies of HRV and the myocardial adrenergic and muscarinic transduction system in ...

Analysis of Heart Rate Variability

Ergonomics, 1973
Spontaneous variability of heart-rate has been related to three major physiological originating factors: quasi-oscillatory fluctuations thought to arise in blood-pressure control, variable frequency oscillations due to thermal regulation, and respiration; frequency selective analysis of cardiac interbeat interval sequences allows the separate ...

Introduction to Heart Rate Variability

2017
Searching on Google Scholar the string “heart rate variability” (HRV) provides about half a million references, which gives us an idea of the research activity around this concept. This chapter describes the historical development of this research field, from the pioneering work of the eighteenth and nineteenth centuries to the boom of the final decade
