This paper introduces the basic concept about HRV and the analysis methods on it, puts forward the system structure of portable spectrum analytic facility for HRV, and presents the analytic algorithms. On analysing the characteristics of the ECG signals, the paper introduces a practicable electrocircuit on sampling ECG signals. This electrocircuit has three amplifiers and gains good performance. The relevant sampling result is also presented. Concerning the analytic algorithms, the paper puts forward the algorithms for temporal analysis and spectrum analysis, and deduces the AR algrithm for spectrum analysis. The analysis result on HRV of an instance is also presented in this paper.
