This investigation involves the non‐invasive collection of data concerning the events associated with spontaneous labor contractions, by the utilization of computer processed abdominal surface potentials (ASP), graphically displayed two dimensionally as topograms. Subjects were 19 healthy women volunteers experiencing normal pregnancies of 37—41 weeks duration who were admitted due to the onset of spontaneous labor. Sixteen of these subjects progressed to normal vaginal deliveries. We were able to classify the electrical events displayed on the topograms into mono‐and multifocal origins of high power areas (HPA), with the monofocal origins leading to synchronous, and the multifocal leading to asynchronous patterns of bioelectric propagation. We feel that the use of topograms may prove to be of clinical value in assessing the progress of labor.
