Abstract

Introduction: The analysis of heart rate variability (HRV) has been used as a resource for the measurement of autonomic nervous system activity in different situations. This analysis is based on identifying the strength of bands of
low and high frequencies of the spectral function of the RR intervals in heart rate. Studies have shown that the related high frequency band parasympathetic tone controls the resting state, while exercise is associated with sympathetic activation, linked to lower frequency bands. The autonomic nervous system plays an important role in mediating
the cardiovascular responses induced by stress. Objective: To describe a technique for analysis of heart rate variability
in the measurement of autonomic nervous system activity. Discussion: To perform HRV analysis the “Nerve-Express”
uses an effective and transparent visual representation, known as rhythmography method which reflects the structure
of HRV wave and acts as a “fingerprint” of autonomic regulatory mechanisms. The wave RR intervals are recorded sequentially forming a rhythmogram, namely a picture of curved wave-specific variability of RR intervals.
