The Cardiovascular Waves Analysis toolbox for Scilab

Participants : Lisa Guigue, Claire Médigue, Michel Sorine, Serge Steer.

The work about Heart Failure with preserved Ejection Fraction required the development of a set of tools for ECG signal manipulation and analysis. These tools, developed by Serge Steer, have been included in a Scilab toolbox named Cardiovascular Waves Analysis toolbox that will be available soon as a Scilab module. It extends the former Cardiovascular Toolbox and provides functions for:

- ECG reading multi channel ECG files in various formats (ISHNE, MIT, TMS32),

- Handling huge ECG files obtained through Holter devices,

- ECG pretreatment (filtering, subsampling, power line interference and base line wander removal),

- ECG events detection (P, Q, R, S, T) peaks, onset and end, based on former tools developed by Qinghua Zhang,

- Cardiovascular signals analysis using various approaches like frequency or time-frequency analysis, complex demodulation, non parametric, multilevel and multifractal methods,

  - Specialized plotting facilities.
