Electrohysterography (EHG) is a non-invasive technique for monitoring uterine electrical activity. However, the presence of artifacts in the EHG signal may give rise to erroneous interpretations and make it difficult to extract useful information from these recordings. The aim of this work was to develop an automatic system of segmenting EHG recordings that distinguishes between uterine contractions and artifacts. Firstly, the segmentation is performed using an algorithm that generates the toco-like signal derived from the EHG and detects windows with significant changes in amplitude. After that, these segments are classified in two groups: artifacted and non-artifacted signals. To develop a classifier, a total of eleven spectral, temporal and non-linear features were calculated from EHG signal windows from 12 women in the first stage of labor that had previously been classified by experts. The combination of characteristics that led to the highest degree of accuracy in detecting artifacts was then determined. The results showed that it is possible to obtain automatic detection of motion artifacts in segmented EHG recordings with a precision of 92.2% using only seven features. The proposed algorithm and classifier together compose a useful tool for analyzing EHG signals and would help to promote clinical applications of this technique. ; R + D + I Linguistic Assistance Office at the UPV ; Ministerio de Ciencia e Innovación de España (TEC2010-16945) ; Ye-Lin, Y.; Garcia Casado, FJ.; Prats Boluda, G.; Alberola Rubio, J.; Perales Marin, AJ.
