Loss of Health is Loss of RhythmActivating the rhythm improves health

Joysys develops and distributes health evaluation and health control technologies.

From the numerous projects focusing on prevention, the knowledge matured that customary instruments in the market used for the precise determination of the heart rate variability (HRV) are not sufficient. Thanks to the close collaboration with the Human Research Institute, Joysys can benefit from more than 25 years of experience in the field of ECG measurement. The result is the 8th generation of ChronoCord®, which takes the lead in the field of HRV instruments worldwide.
