BackgroundFresh stillbirths (FSB) and very early neonatal deaths (VEND) are important global challenges with 2.6 million deaths annually. The vast majority of these deaths occur in low- and low-middle income countries. Assessment of the fetal well-being during pregnancy, labour, and birth is normally conducted by monitoring the fetal heart rate (FH...
Fetal Heart Rate (FHR) monitoring is used in every day clinical practice to help obstetricians assess fetal health status during delivery. However, the detection of fetal acidosis that allows relevant decisions for operative delivery remains a challenging task. This project aims to create a machine learning model for FHR classification that can pre...

Recent studies suggest that intrapartum ZigZag pattern of fetal heart rate (FHR) is significantly associated with cord blood acidaemia and neonatal complications. For the clinical significance of this pattern, it is mandatory that ZigZag episodes in cardiotocographic (CTG) recording are correctly identified. The aim of the present study was to exam...

During labor, fetal heart rate (FHR) is monitored externally using Doppler ultrasound. This is done continuously, but for various reasons (e.g., fetal or maternal movements) the system does not record any samples for varying periods of time. In many settings, it would be quite beneficial to estimate the missing samples. In this paper, we propose a ...

Objective In 2015, new FIGO guidelines for CTG interpretation were presented (FIGO-15). In 2017, the previous Swedish guidelines (SWE-09) were replaced with guidelines adapted to FIGOs (SWE-17). The performance of these three templates had not been scientifically evaluated before its clinical implementation. The objective of this study was to compa...

According to previous studies, after in vitro fertilization-embryo transfer (IVF-ET) there exist a high early pregnancy loss (EPL) rate. The objectives of this study were to construct a prediction model of embryonic development by using machine learning algorithms based on historical case data, in this way doctors can make more accurate suggestions...

Abstract—Background: cardiotocography (CTG) has long been used in clinical decision making to help assess the fetus’ condition during pregnancy. However it’s usefulness in the detection of fetal acidosis is debated due to high inter and intraobserver variability and general difficulty in interpreting the signals. The introduction of automatic analy...

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...

The proposed dataset provides annotations for the 552 cardiotocographic (CTG) recordings included in the publicly available “CTU-CHB intra-partum CTG database” from Physionet ( https://physionet.org/content/ctu-uhb-ctgdb/1.0.0/ ). Each CTG recording is composed by two simultaneously acquired signals: i) the fetal heart rate (FHR) and ii) the matern...
