摘要:
A computer-assisted method for quantitative analysis of respiratory sinus arrhythmia (RSA) includes obtaining a time series of a cardiac interval signal from an individual, obtaining a time series of a respiratory signal from the individual decomposing the cardiac interval signal into a first group of ensemble empirical modes obtaining, by a computer system, a time series of RSA instantaneous amplitude from at least one of the first group of ensemble empirical modes decomposing the respiratory signal into a second group of ensemble empirical modes obtaining a time series of respiratory instantaneous phase from the one of the second group of ensemble empirical modes determining respiratory period from the time series of the respiratory instantaneous phase and quantifying RSA in the individual according to a dependence of the RSA instantaneous amplitude on the respiratory period.
