Abstract
The invention discloses an heart rate variability (HRV) analyzing device, which integrates the ECG signal measuring and processing technology and combines the HRV analyzing functions. The device adopts sensing electrodes disposed thereon or external sensing electrodes to record a subject'"'"'s ECG signals. After being amplified, filtered and analog-to-digital converted, the ECG signals are transmitted to a built-in CPU to proceed with time domain and frequency domain analysis, and the results of the analysis are shown on a display unit. In such a way, the signal acquisition, algorithm calculation and display can be completed in the single device of the invention, which simplifies the conventional instruments and equipment, and provides an indication of the subject'"'"'s health state in the aspect of self-health care.
