Kubios HRV is an advanced tool for studying the variability of heart beat intervals. Due to its wide variety of different analysis options and the easy to use interface, the software is suitable for researchers and clinicians with varying premises. The software is mainly designed for the analysis of normal human HRV, but should also be usable for animal researchers.

See details of the features from the Kubios HRV User's Guide.
  • An easy-to-use graphical user interface
  • Read support for ECG data (ASCII ECG data and EDF, GDF and Biopac AcqKnowledge file formats) and RR interval data (ASCII RR interval, Suunto SDF/STE/XML, Polar HRM and Garmin FIT files).
  • Tools for RR interval artifact correction
  • Versatile analysis options including
    • The most common time-domain (mean/STD of RR intervals, RMSSD, pNN50, etc.) and frequency-domain (VLF, LF, and HF band powers and peak frequencies) measures. In the frequency-domain analysis the power spectrum is calculated by using a traditional FFT based method and a parametric method based on autoregressive time series modeling
    • Several nonlinear methods such as Poincare plot, approximate/sample entropy, detrended fluctuation analysis (DFA), recurrence plot analysis, and correlation dimension
  • Advanced detrending options for removing disturbing low frequency baseline trend components
  • The detailed report sheets can be printed or saved in many Portable Document Format (PDF). Results can also be saved as an ASCII text file in two different formats (SPSS friendly format as a new feature) which can easily be imported into, e.g., Microsoft Excel.
