Kubios HRV Standard

A freeware heart rate variability analysis software for non-commercial personal use:

  • Supports RR data from HR monitors (Polar, Suunto, Garmin)
  • Computes all commonly used time- and frequency-domain as well as several nonlinear HRV parameters
  • Analysis results can be exported in CSV and PDF format
Analysis results reflect changes in cardiac autonomic regulation and can be used for example to assess stress and recovery.

Kubios HRV is developed by an experienced team of medical physicists from Kuopio, Finland. The first version of Kubios HRV was released in 2004 and the software has been used in over 800 scientific studies by now. Download Kubios HRV Standard now and start exploring your HRV.

Heart rate variability analysis software

Data support and pre-processing

Support for Polar, Suunto and Garmin HR monitor data as well as RR interval ASCII text files. Note that beat-to-beat RR interval data is required for HRV analysis.

Pre-processing options include correction of artefacts in RR interval time series using adjustable thresholds. In addition, baseline trends can be removed from the RR data to focus the analysis on the components reflecting sympathetic and parasympathetic regulation of heart rate.

Analysis methods and functionality

The analysis methods include all standard time-domain and frequency-domain methods and several nonlinear methods.

  • Time-domain: Mean RR, SDNN, RMSSD, pNN50 etc.
  • Frequency-domain: VLF, LF and HF band powers, peak  frequencies and LF/HF ratio
  • Nonlinear: Poincaré plot, ApEn, SampEn and DFA

Analyses can be easily performed for a selected number of time periods.

Reports and interpretations

Analysis results can be saved in the form of a detailed PDF report or results can be saved into an ASCII text file.

Results are computed according to existing guidelines for HRV analysis and are thus comparable to reference values found from literature.
