Noninvasive FECG for estimating the fetal heart rate [PDF]

, 2013
Decelerations of fetal heart rate have been known to be associated with fetal distress. Continuous fetal heart rate monitoring was expected to result in dramatic reduction of undiagnosed fetal hypoxia, but the outputs of FHR monitors were often ...

Maternal, fetal and neonatal heart rate and heart rate variability in Holstein cattle

Pesquisa Veterinária Brasileira, 2019
: The aim of this study was to describe the normal values for maternal, fetal and neonatal heart rate (HR) and heart rate variability (HRV) indexes in the time domain (standard deviation of beat-to-beat interval - SDNN; root mean square of successive ...

Improvements in fetal heart rate analysis by the removal of maternal-fetal heart rate ambiguities [PDF]

BMC Pregnancy and Childbirth, 2015
Misinterpretation of the maternal heart rate (MHR) as fetal may lead to significant errors in fetal heart rate (FHR) interpretation. In this study we hypothesized that the removal of these MHR-FHR ambiguities would improve FHR analysis during the final hour of labor.Sixty-one MHR and FHR recordings were simultaneously acquired in the final hour of ...

Unrecognized maternal heart rate artefact in cases of perinatal mortality reported to the United States Food and Drug Administration from 2009 to 2019: a critical patient safety issue

BMC Pregnancy and Childbirth, 2019
Background Maternal 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.

Effectiveness of ambulatory non‐invasive fetal electrocardiography: impact of maternal and fetal characteristics

Acta Obstetricia et Gynecologica Scandinavica, 2023
Introduction Non‐invasive fetal electrocardiography (NIFECG) has potential benefits over the computerized cardiotocography (cCTG) that may permit its development in remote fetal heart‐rate monitoring.

Fetal ECG Arrhythmia Detection Based on DensNet Transfer Learning

Frontiers in Biomedical Technologies, 2023
Purpose: The mortality rate of fetuses due to heart defects is a major concern for clinicians. The fetus's heart is monitored non-invasively using the abdominal Electrocardiogram (ECG) of the mother.

Fetal heart rate throughout gestation.

, 2022
Fetal heart rate was monitored biweekly by ultrasound on high-dose (1x108 PFU ZIKV-DAK) dams to confirm fetal viability. The horizontal, dotted lines on the graph represent the range of normal heart rates for fetuses at WNPRC.

Prenatally diagnosed fetal heart rhythm abnormalities—incidence, diagnosis and outcome

Clinical and Experimental Obstetrics & Gynecology, 2022
Backrounds: Fetal arrhythmias represent a significant cause of fetal morbidity and mortality and occur in approximately 1–3% of pregnancies. The unknown fetal arrhythmias are the cause of intrauterine fetal demise in as many as 3–10% of cases, as well as

The use of ultrasonographic measurement of the heart size and fetal heart rate variation for gestational age determination in local Bulgarian goats

Veterinary Medicine and Science, 2021
Background Determination of gestational age in goats was performed using ultrasound measurements of different fetal biometric parameters. There are no data showing quadratic and exponential dependence between fetal heart parameters and gestational age ...
