Cardiotocography (CTG) has been the primary tool for monitoring the fetal health during antepartum and intra-partum period since the 1960s. It works by recording both fetal heart rate and mother’s uterine contraction pressure simultaneously. However, due to lack of consensus in the interpretation of features and due to inter- and intra-clinician va...

BackgroundFetal heart rate (FHR) monitoring is a screening tool used by obstetricians to evaluate the fetal state. Because of the complexity and non-linearity, a visual interpretation of FHR signals using common guidelines usually results in significant subjective inter-observer and intra-observer variability. Objective: Therefore, computer aided d...

Background: While late decelerations and major bradycardia episodes in intrapartum cardiotocography (CTG) recordings are known to correlate with fetal distress,little is known of the importance of the saltatory pattern. Objective: The aim of the study was to examine whether the fetal heart rate (FHR) saltatory pattern in intrapartum CTG registratio...

BackgroundMaternal heart rate artefact is a signal processing error whereby the fetal heart rate is masked by the maternal pulse, potentially leading to danger by failure to recognize an abnormal fetal heart rate or a pre-existing fetal death. Maternal heart rate artefact may be exacerbated by autocorrelation algorithms in modern fetal monitors due...

Prenatal stress (PS) during pregnancy affects in utero- and postnatal child brain-development. Key systems affected are the hypothalamic-pituitary-adrenal axis and the autonomic nervous system (ANS). Maternal- and fetal ANS activity can be gauged non-invasively from transabdominal electrocardiogram (taECG). We propose a novel approach to assess cou...

IntroductionCardiotocography (CTG) consists of two biophysical signals that are fetal heart rate (FHR) and uterine contraction (UC). In this research area, the computerized systems are usually utilized to provide more objective and repeatable results.Materials and MethodsFeature selection algorithms are of great importance regarding the computerize...

BackgroundRegular fetal heart rate monitoring during labor can drastically reduce fresh stillbirths and neonatal mortality through early detection and management of fetal distress. Fetal monitoring in low-resource settings is often inadequate. An electronic strap-on fetal heart rate monitor called Moyo was introduced in Tanzania to improve intrapar...

Fetal heart rate variability (FHRV) has long been recognised as a powerful predictor of fetal wellbeing, and a decrease in FHRV is associated with fetal compromise. However, the mechanisms by which FHRV is reduced in the chronically hypoxic fetus have yet to be established. The sympathetic and parasympathetic influences on heart rate mature at diff...

To assess the current use of a five-tier fetal heart rate (FHR) classification system (National College of French Obstetricians and Gynecologists, CNGOF, 2007) and of a three-tier system (Federation International of Gynecology and Obstetrics, FIGO, 2015). This was a single-center prospective study conducted in April 2016. Midwives were asked to cla...

Cardiotocography (CTG) is applied routinely for fetal monitoring during the perinatal period to decrease the rates of neonatal mortality and morbidity as well as unnecessary interventions. The analysis of CTG traces has become an indispensable part of present clinical practices; however, it also has serious drawbacks, such as poor specificity and v...
