摘要：

We investigate the phase synchronization of heartbeat and respiration in a group of healthy infants. Having presented and compared two quantitative measures of synchronization, we conclude that one of these measures - the conditional probability index - allows reliable detection of synchronous epochs of different order n : m and, thus, makes possible an automatic processing of large data sets: In our analysis of experimental time series, we have found numerous epochs of phase synchronization. It turned out that the average degree of synchronization varies with the age of the newborns.
