Automatic far-end control method for evaluating autonomic nervous system function and its system

The present invention relates to an autoamtic remote control method for estimating hart rate variability (HRV). Said method is characterized by that the signal of heart rate of user can be collected,digitized and implied at the customer terminal of a master-slave system, then these digitized signals can be transferred into service terminal by means of a network system, in which its automatic ANSfunctions analysis system can be used for on-line analyzing these digitized signals, and can provide index of autonmoic nervous system, and can transfere these indexes into user (customer terminal) and/or medical specialist for making further verification and help.
