A kind of Heart Rate Variability (for short HRV) analysis system is introduced in this paper, which is consisted of modules of ECG amplifier, A/D converter, arrhythemia analysis, HRV analysis. Quantitative results of time domain and frequency domain analysis can be obtained and represented more intuitively by graphics, such as Lorenz scatter, R R interval histogram, etc. The purpose of the study of this system is to provide some objective and quantitative methods to estimate autonomic nerve function in comb...
