Research of HRV and PRV under Electronic Synchronous Acquisition System

Abstract

Abstract. In order to discuss the unity of heart rate variability (HRV) and pulse rate variability (PRV) and explore the relationship between HRV/PRV and the autonomic nervous. R-R intervals and P-P intervals were obtained from ECG and pulse signals of 17 healthy volunteers by synchronous acquisition system. HRV and PRV were analyzed offline by spectral analysis. And PRV derived from pulse wave corresponds well to traditional HRV derived from ECG. The results indicate that PRV and HRV had the same features which synchronous acquisition ECG and pulse wave, and the PRV may replace HRV to estimate the excitement of autonomic nervous.
