SYMBIOFI is committed to the highest standards of scientific excellence
SYMBIOLINE Professional includes a built-in measurement engine allowing to analyze heart rate variability. This measurement engine has been developped by Lille CHRU, and meets the highest standards of scientific excellence.
Developed by French state-supported biomedical research teams, our measurement engine is based on two patented, research-validated devices :
- Patent 1 : Method and device for filtering a series of cardiac rhythm signals (RR) derived from a cardiac signal, and more particularly an ECG signal.
The device is used to guarantee optimal accuracy and to eliminate artefacts when analyzing heart rate variability.
- Patent 2 : Method and device for evauating pain and stress in a living being.
The device is used to analyze heart rate variability and to use resulting data to calculate the cardiac coherence parameter.
