Ready-to-use HRVUAB program computes HRV via spectral analysis with preliminary results.
The paper introduces HRVUAB, a ready-to-use program for computing heart rate variability using spectral analysis techniques.
HRVUAB may aid HRV spectral analysis in research; leaves open clinical validation and adoption.
The application of spectral analysis techniques to study the nervous modulation of the vertebrate heart have given interesting results in clinical studies although nearly nothing is known in lower vertebrates. A program to compute this heart rate variability is described in detail and preliminary results are shown. Data is first statistically qualified and fragmented in smaller segments, each being further processed through linear trend removal and normalization before the application of the Fast Fourier Transform algorithm to estimate the interval spectrum. All consecutive periodograms are averaged and the interval spectrum plotted and saved.

Altimiras et al. (1994) studied Heart rate variability. HRVUAB program was evaluated. A ready-to-use program, HRVUAB, was developed to compute heart rate variability using spectral analysis techniques, including Fast Fourier Transform, with preliminary results demonstrated.
