gVARVI: Graphic utility for heart rate Variability Acquisition in Response to Visual stImuli

gVARVI is an utility to retrieve heart rate data from heart rate sensors while some audiovisual stimuli is being played. Specifically gVARVI retrieves RR-data (time gap between two consecutive heart beats). It is simple an intuitive, with a clean graphic interface.

gVARVI supports Polar iWL® and all ANT+ heart rate sensors (it was tested with Garmin Soft Strap Premium Heart Rate Monitor) and allows users to automatically search available sensors.

gVARVI provides a simple and clean interface, storing adquisition configurations as "activities".

What is VgeneRepertoire.org?

It is a database repository for variable (V) exon sequences that encode immunoglobulin (IG) and T-cell receptor (TR) molecules, providing support to immunologists interested in these molecules and aids in comparative phylogenetic studies.

The database contains sequences from jawed vertebrate taxa whose WGS datasets are available.

To date, the repository consist of more than 20,000 V exon (parts of V-gene) sequences from more than 100 taxa (orders mammalia, reptilia, birds, and fishes).

gHRV: graphical tool for HRV analysis

gHRV is a graphical tool for clinicians and researchers interested in Heart Rate Variability Analysis. The objective of gHRV is to be powerful and easy to use and install. gHRV is distributed as free software (GNU GPL License) and binary packages are available for Windows, MacOSX and Ubuntu/Debian systems.

Binaries and documentation of gHRV can be found in http://ghrv.milegroup.net

RHRV: R package for analyzing HRV

RHRV is an open source package for the R environment that provides a complete set of tools for analyzing Heart Rate Variability (HRV). RHRV comprises a complete set of tools for HRV analysis allowing users to import data files containing heartbeat positions in the most broadly used formats; eliminating outliers or spurious points present in the time series with unacceptable physiological values; plotting HRV data and performing time domain, frequency domain and nonlinear HRV analysis. RHRV is the first R package for HRV analysis.

You can find video tutorials, documentation and examples in http://rhrv.r-forge.r-project.org

The CRAN page of RHRV is here.

VARVI: a software tool for analyzing the HRV in response to visual stimuli

VARVI (heart rate Variability Analysis in Response to Visual stImuli) is a free software tool developed to perform heart rate variability (HRV) analysis in response to different visual stimuli. The tool was developed after realizing that this type of studies are becoming popular in fields such as psychiatry, psychology and marketing, and taking into account the lack of specific tools for this purpose.

VARVI allows the users to obtain Heart Rate (HR) records from subjects who are watching video files. Each video file will be labelled with a tag, and the HR record will contain information of these tags with their corresponding time intervals.
