Fetal heart rate and fetal heart rate variability in Lipizzaner broodmares [PDF]

Acta Veterinaria Hungarica, 2015
Monitoring fetal heart rate (FHR) and fetal heart rate variability (FHRV) helps to understand and evaluate normal and pathological conditions in the foal.

Non-reassuring fetal heart rate and associated factors among laboring mothers at southern public hospitals in Ethiopia: a poisson regression model [PDF]

Scientific Reports
Non-reassuring fetal heart rate is a critical indicator of fetal well-being. It is used to predict fetal hypoxia and metabolic acidosis due to insufficient fetal oxygenation and is the major contributor to perinatal mortality and morbidity.

Evaluation and patient experience of wireless noninvasive fetal heart rate monitoring devices [PDF]

Acta Obstetricia et Gynecologica Scandinavica
Introduction In clinical practice, fetal heart rate monitoring is performed intermittently using Doppler ultrasound, typically for 30 minutes. In case of a non‐reassuring heart rate pattern, monitoring is usually prolonged.

Fetal Heart Rate Preprocessing Techniques: A Scoping Review [PDF]

Bioengineering
Monitoring fetal heart rate (FHR) through cardiotocography is crucial for the early diagnosis of fetal distress situations, necessitating prompt obstetrical intervention. However, FHR signals are often marred by various contaminants, making preprocessing

The Approach to Sensing the True Fetal Heart Rate for CTG Monitoring: An Evaluation of Effectiveness of Deep Learning with Doppler Ultrasound Signals [PDF]

Bioengineering
Cardiotocography (CTG) is widely used to assess fetal well-being. CTG is typically obtained using ultrasound and autocorrelation methods, which extract periodicity from the signal to calculate the heart rate.

Assessments of Heart Rate and Sympathetic and Parasympathetic Nervous Activities of Normal Mouse Fetuses at Different Stages of Fetal Development Using Fetal Electrocardiography

Frontiers in Physiology, 2021
Heart rate is controlled by the activity of the autonomic nervous system: the sympathetic and parasympathetic nervous systems increase and suppress heart rate, respectively.

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 ...

Assessment of fetal heart rate variability and velocity variability by Doppler velocimetry of the descending aorta at 10-20 weeks of gestation [PDF]

, 1999
Objectives: Determination of gestational age-related modulations in fetal heart rate and descending aorta blood flow velocity in the early human fetus and comparison of aortic variability data with data obtained from the umbilical artery.

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
