Variations on fetal heart rate variability [PDF]
The Journal of Physiology, 2016 Intrapartum electronic fetal monitoring (EFM) is widely used throughout the developed and developing world. This practice is based on the understanding that fetal heart rate (FHR) is sensitive to hypoxia. During labour, the fetus may be exposed to acute hypoxia during uterine contractions or intrapartum insults, and has well‐established cardiovascular ...

New Estimators and Guidelines for Better Use of Fetal Heart Rate Estimators with Doppler Ultrasound Devices [PDF]
Comput. Math. Methods Medicine, 2014 Characterizing fetal wellbeing with a Doppler ultrasound device requires computation of a score based on fetal parameters. In order to analyze the parameters derived from the fetal heart rate correctly, an accuracy of 0.25 beats per minute is needed ...

A Comprehensive Review of Techniques for Processing and Analyzing Fetal Heart Rate Signals
Italian National Conference on Sensors, 2021 The availability of standardized guidelines regarding the use of electronic fetal monitoring (EFM) in clinical practice has not effectively helped to solve the main drawbacks of fetal heart rate (FHR) surveillance methodology, which still presents inter-

Unsupervised Learning-Based Non-Invasive Fetal ECG Muti-Level Signal Quality Assessment
Bioengineering, 2023 Objective: To monitor fetal health and growth, fetal heart rate is a critical indicator. The non-invasive fetal electrocardiogram is a widely employed measurement for fetal heart rate estimation, which is extracted from the electrodes placed on the ...

A dilated inception CNN-LSTM network for fetal heart rate estimation
Physiological Measurement, 2021 Objective. Fetal heart rate (HR) monitoring is routinely used during pregnancy and labor to assess fetal well-being. The noninvasive fetal electrocardiogram (ECG), obtained by electrodes on the maternal abdomen, is a promising alternative to standard ...

Fetal heart rate development during labour
BioMedical Engineering OnLine, 2021 Background Fresh 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
