Loss of Health is Loss of RhythmActivating the rhythm creates health again

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 has more than 25 years of experience in the field of ECG measurement. The result is ChronoCord® the 8th generation, which takes the lead in the field of HRV instruments worldwide.


Chronobiology studies the temporal organization of physiological and psychological processes and repetitive patterns of behavior of organisms that are affected endogenously or exogenously.


Our ChronoCord® HRV measuring devices have been further developed in scientific projects and together with intelligent software systems they are now used in a variety of health-related applications.
