Description
  • Fetal heart rate (fHR) is used to evaluate fetal well-being during delivery. It provides information of fetal status and allows doctors to detect ongoing hypoxia. The routine intrapartal evaluation is based on description of macroscopic morphological features of the fHR baseline. FHR contains more information than is used so far, therefore in this work we have focused on evaluation of nonlinear features for fHR signal description. Our data set consists of 189 recordings. Signals with umbilical artery pH less then 7.15 were considered pathological. From each record 20-minute segment directly preceding the delivery was chosen. Fractal dimension of attractor, fractal dimension of waveform, entropy, and complexity were used as features. All features were evaluated using Mann-Whitney U test and those fulfilling the statistical significance with p < 0.01 were used for further computations. Ten fold cross-validation method was used for estimation of classification performanc
