Analisi HRV - Analisis variabilità
della frequenza cardiaca

 

They allow analysis of the autonomic nervous system. The questions that arises is: which measured value is the most efficient for analyzing the functional status of the autonomic nervous system? The main consideration is the heart. The change in heart rate is a universal reaction of the entire body to any impact from environmental reactions. The traditional method for measuring average heart rate only mirrors the "end effect" of the numerous regulation impacts on the cardiovascular system. Two people with the same average heartrate could then have different autonomic regulation conditions. That is, the same average heart rate can correspond to various activity combinations of the chain links of the system controlling the autonomic homeostasis.

The rhythm of the heart is based on the interplay between the tension (left) and relaxation (right) of the heart chambers

This can be measured by the Heart Rate Variability (HRV). The variability of the heart rate refers to the degree of fluctuation in the length of the intervals between heart beats.
