It is mainly based on the monitoring and evaluation of the fetal heart rate (FHR) signal, which has to be interpreted online. Evaluation and interpretation of FHR gives an indication of the fetal condition. A lot of research efforts have been done towards the development of automatic and

continuous monitoring of the FHR, was introduced into clinical practice in the late 1960s and since then it has been considered as an indispensable
tool for fetal surveillance. However, EFM evaluation and its merit is still an open field of controversy, mainly because it is not consistently
reproducible and effective. In this work, we present a novel method based on grammatical evolution to discriminate acidemic from normal fetuses,
utilizing features extracted from the FHR signal during the minutes immediately preceding delivery. The proposed method identifies linear and
nonlinear correlations among the originally extracted features and creates/constructs a set of new ones, which, in turn, feed a nonlinear classifier.
The classifier, which also uses a hybrid method for training, along with the constructed features was tested using a set of real data achieving an
overall performance of 90% (specificity = sensitivity = 90%).
