Abstract
Preterm birth is the leading cause of a neonatal death, so it is extremely important to distinguish the pregnancy at risk of preterm threatening labour. Monitoring an electrical activity of the uterine muscle seems very promising as a method which enables noninvasive recording of good quality electrohysterographic signals. The developed instrumentation enabled recording of signals by means of electrodes attached to abdominal wall and determination of quantitative parameters describing the contractions detected. Our research material comprised 3 groups of patients: with physiological pregnancy, with the symptoms of premature threatening labour and patients during at term labour. The classification of uterine activity signals in each pair of groups was made using nonlinear Lagrangian Support Vector Machines which allows for improving the computational efficiency and learning quality of the SVM algorithm. The obtained results show that the proposed approach is able to differentiate between the contractile activity in physiological pregnancy and that connected with a risk of premature labour. Identification of these high-risk pregnancies leads to an enhanced perinatal surveillance.
