Abstract—In this paper, a bispectrum analysis technique is Arrhythmia analysis [9], the Heart Rate Variability (HRV)
suggested for quantitative analysis of Congestive Heart Failure analysis [10, 11], and so on [12-14].
(CHF). The bispectrum is estimated using an autoregressive
model, and the frequency coupling of the bispectrum is extracted A Pulse Rate Variability (PRV) analysis based on
as a quantitative measure to classify normal and CHF subjects. bispectrum analysis was introduced in this paper. According to
According to the further study of the foot to peak interval analyzing three PRV series, corresponding quantitative
variability (FPIV), the peak to notch interval variability (PNIV) parameters were obtained. Moreover, the differences of these
