gHRV

A graphical tool for Heart-Rate Variability analysis

gHRV is a graphical tool to clinicians and researchers interested in Heart Rate Variability Analysis. The objective of gHRV is to be powerful and easy to use and install. Main features: - Reads Polar, Suunto, ASCII (beats and RR series) and WFDB (qrs) beats files. - Episodes can be read from ASCII files, inserted, edited and deleted. gHRV includes both a graphical and a spreadsheet-like tools for editing episodes. - Time-domain, frequency-domain and non-linear analyses are included. Some of the included measures are: * Time-domain: SDNN, SDANN, rMSSD, SDNN index, pNN50, HRV triangular index and TIN. * Frequency-domain: power in ULF, VLF, LF and HF bands, total power and LF/HF ratio. * Non-linear: approximate entropy, fractal dimension and SD1 and SD2 from Poincaré plots. - It generates high-quality plots that can be exported in eps, tiff, svg, png, pdf and jpg formats. - It shows reports that can be saved in html format. - Temporal evolution of frequency-domain and non-linear parameters can be represented and significance tests of these paremeters in different areas can be performed.
