Abstract

The fast uterine electrical activity during parturition is analysed through two signals recorded on the abdominal wall. After differential amplification and filtration the fast activity is numerically processed to obtain quantified information for monitoring labour progress. Through parametric modellíng, the necessary data for the study of the EMG signal at each contraction is reduced to six. Moreover, an attempt was made to measure the velocity of electrical wave propagation across the uterus from the delay of the cross-correlation function maximum of the two signals.
