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

Journal of Physiology, 2019 We introduce a technique to test whether intrinsic fetal heart rate variability (iFHRV) exists and we show the utility of the technique by testing the hypothesis that iFHRV is affected by chronic fetal hypoxia, one of the most common adverse outcomes of ...

Fetal heart rate following coelocentesis
The Journal of Maternal-Fetal Medicine, 1997 For psychological reasons, coelocentesis was performed in 20 women prior to termination of pregnancy, at 6-11 weeks of gestation. The fetal heart rate (FHR) was measured immediately before the procedure and at 1, 5, and 10 min afterward. There was no significant difference between FHR before coelocentesis compared to the values at 1 min (mean = 158 ...

Extracting fetal heart beats from maternal abdominal recordings: Selection of the optimal principal components [PDF]
, 2014 This study presents a systematic comparison of different approaches to the automated selection of the principal components (PC) which optimise the detection of maternal and fetal heart beats from non-invasive maternal abdominal recordings.

Effects of three different stimulations (acupuncture, moxibustion, acupuncture plus moxibustion) of BL.67 acupoint at small toe on fetal behavior of breech presentation [PDF]
, 2007 The aim of the study was to evaluate cardiovascular effects and fetal behavior during moxibustion, acupuncture or acupuncture plus moxibustion applied on the BL.67 acupoint of women (beside the outer corner of the 5th toenail) in fetal breech ...

A clustering-based method for single-channel fetal heart rate monitoring
PLoS ONE, 2018 Non-invasive fetal electrocardiography (ECG) is based on the acquisition of signals from abdominal surface electrodes. The composite abdominal signal consists of the maternal electrocardiogram along with the fetal electrocardiogram and other electrical ...

Sinusoidal fetal heart rate pattern [PDF]
, 2016 We describe 2 cases of term anemic fetuses with different sinusoidal pattern morphology, and possible mechanisms.nbspCasesmdashThe first patient noted sudden cessation of fetal movement on the day of presentation. She had a sinusoidal FHR pattern.

Hybrid methods based on empirical mode decomposition for non-invasive fetal heart rate monitoring [PDF]
, 2020 This study focuses on fetal electrocardiogram (fECG) processing using hybrid methods that combine two or more individual methods. Combinations of independent component analysis (ICA), wavelet transform (WT), recursive least squares (RLS), and empirical ...
