Abstract

Assisted reproductive technologies are increasingly common due to the rising maternal age. One potential cause of embryo implantation failure is altered uterine peristalsis patterns. Intracavitary electrohysterography (IC-EHG) is a recent technique developed to characterize the electrophysiology of uterine peristalsis throughout the menstrual cycle. Two primary methodologies are employed for analysis: Contraction Analysis and Window Analysis. This study aims to examine the relationship between parameters describing the same characteristics of the signals using contraction and window analysis of 2, 4 and 10 minutes. Peristalsis was recorded at three different menstrual cycle phases from 10 fertile healthy women. Continuous 10 minutes recordings free of artifacts were selected. A very strong linear relationship (R2 ≥ 0.95) was found between the amplitude parameter from contraction (Root Mean Square (RMS)) and window (80th percentile of signal RMS envelope) analysis. For the spectral parameter (Median Frequency), the relationship was strong (0.59 ≤ R2 ≤ 0.75), while for the non-linear parameter (Sample Entropy), it was moderate (0.19 ≤ R2 ≤ 0.29). Strongest relationships were obtained with 2-minutes windows. The findings suggest that window analysis can accurately assess contraction intensity and, more moderately its spectral content; but basal segments in window analysis significantly influence the signal complexity parameter.
