Uterine EMG : Experimental And Mathematical Determination Of The Relationship Between Internal And External Recordings

Abstract

Several methods are tested in order to show or to model the relationship between internal and external recordings of uterine elecmcal activity, related to mechanical effect. Most of them attempt to establish a linear model of propagation. It is shown that the correlation only exists when reducing the signals to presence or absence of events. On the other hand, it is confiied that no classical propagation can be observed for that kind of signals.
