Feasibility and Analysis of Bipolar Concentric Recording of Electrohysterogram with Flexible Active Electrode [PDF]
Annals of Biomedical Engineering, 2014 The conduction velocity and propagation patterns of the electrohysterogram (EHG) provide fundamental information on the electrophysiological condition of the uterus. However, the accuracy of these measurements can be impaired by both the poor spatial selectivity and sensitivity to the relative direction of the contraction propagation associated with ...

The Icelandic 16-electrode electrohysterogram database [PDF]
Scientific Data, 2015 AbstractExternal recordings of the electrohysterogram (EHG) can provide new knowledge on uterine electrical activity associated with contractions. Better understanding of the mechanisms underlying labor can contribute to preventing preterm birth which is the main cause of mortality and morbidity in newborns.

Optimization of Imminent Labor Prediction Systems in Women with Threatened Preterm Labor Based on Electrohysterography [PDF]
Sensors, 2021 Preterm birth is the leading cause of death in newborns and the survivors are prone to health complications. Threatened preterm labor (TPL) is the most common cause of hospitalization in the second half of pregnancy.

A Preliminary Exploration of the Placental Position Influence on Uterine Electromyography Using Fractional Modelling [PDF]
Sensors, 2022 The uterine electromyogram, also called electrohysterogram (EHG), is the electrical signal generated by uterine contractile activity. The EHG has been considered an expanding technique for pregnancy monitoring and preterm risk evaluation.

Investigating the role of maternal heart rate variability in the onset of labor [PDF]
Frontiers in MedicineThere are currently no measures to accurately predict the onset of labor at term. Currently, the onset of labor is anticipated based on the estimated due date (EDD), which is derived from the day of the last menstrual period or ultrasound-based ...
