Since the cardiotocographic (CTG) monitoring of fetal health, during pregnancy and labor, was introduced, perinatal mortality and morbidity are very reduced. However, inter-observer and intra-observer variability in the interpretation of CTGs requires new researches to improve monitoring efficacy. CTG interpretation variability is also due to the lack of objective and reproducible analysis methods. Different fetal behavioural states cause CTGs signal variation; moreover, behavioural states are expression of fetal maturity. Automatic systems able to classify Fetal Heart Rate signal tracts, can improve FHR analysis reliability. The aim of this work is to present an algorithm to identify Fetal Heart Rate segments with homogenous characteristics, related to four categories of Fetal Heart Rate segments: very reduced variability (1), waving (2), reduced waving (3), very high variability (4). These categories can be closely related to different fetal behavioural states (quiet sleep, active sleep, quiet awake, active awake).

Abstract
Since the cardiotocographic (CTG) monitoring of fetal health, during pregnancy and labor, was introduced, perinatal mortality and morbidity are very reduced. However, inter-observer and intra-observer variability in the interpretation of CTGs requires new researches to improve monitoring efficacy. CTG interpretation variability is also due to the lack of objective and reproducible analysis methods. Different fetal behavioural states cause CTGs signal variation; moreover, behavioural states are expression of fetal maturity. Automatic systems able to classify Fetal Heart Rate signal tracts, can improve FHR analysis reliability. The aim of this work is to present an algorithm to identify Fetal Heart Rate segments with homogenous characteristics, related to four categories of Fetal Heart Rate segments: very reduced variability (1), waving (2), reduced waving (3), very high variability (4). These categories can be closely related to different fetal behavioural states (quiet sleep, active sleep, quiet awake, active awake).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
