Quantified comparison of uterine electrical activity during active labor at various locations NN abdominal surface: A preliminary study

Electrohysterography or the study of the electrical propagation patterns of the uterine contractile activity when combined with modern computing capabilities can prove to be a powerful tool in obstetric care. In this preliminary study the electrical activity during labor contractions was compared quantitatively at various locations on the abdominal surface. Data was collected from 10 participants for about 30 minutes using 7 electrodes mono-polar configuration. The electrical activity was found to be concentrated along the umbilical axis. The center of the electrical activity was found to be non-stationary and move from the lower to the upper uterine segment as the contraction intensified. The quantified electrical activity at various locations may serve as a template for placement of electrodes for future studies.
