Fetal Doppler Simulator Based on Arduino [PDF]

open access: yes, 2020
Heart rate of the fetal is the main indicator of the fetal life in the womb. Monitoring fetal heart rate can't be done, so a tool is needed to monitoring fetal heart rate. Fetal heart rate can be monitored with fetal doppler.

Effects of three different stimulations (acupuncture, moxibustion, acupuncture plus moxibustion) of BL.67 acupoint at small toe on fetal behavior of breech presentation [PDF]

open access: yes, 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 ...

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

open access: yesVeterinary 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 ...

Extracting fetal heart beats from maternal abdominal recordings: Selection of the optimal principal components [PDF]

open access: yes, 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.

Detection of atrial fibrillation episodes in long-term heart rhythm signals using a support vector machine [PDF]

open access: yes, 2020
Atrial fibrillation (AF) is a serious heart arrhythmia leading to a significant increase of the risk for occurrence of ischemic stroke. Clinically, the AF episode is recognized in an electrocardiogram.

New estimators and guidelines for better use of fetal heart rate estimators with Doppler ultrasound devices [PDF]

open access: yes, 2013
International audienceCharacterizing 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

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

open access: yesClinical 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

Amélioration de l'estimation du rythme cardiaque foetal en utilisant les signaux Doppler directionnels et YIN [PDF]

open access: yes, 2012
National audienceTechniques dedicated to the fetal heart rate detection identify the patterns that repeat themselves over the time. The heart rate estimation is algorithmically similar to the estimation of the fundamental frequency (pitch) of voice ...

Fetal heart rate throughout pregnancy

open access: yesAmerican Journal of Obstetrics and Gynecology, 1972
Abstract Serial fetal heart rate (FHR) determinations were made from early pregnancy to term in 24 healthy fetuses by means of an ultrasonic device. A decreasing FHR pattern was noticed from the eleventh through the thirtieth weeks, after which the values remained more stable (about 140 beats per minute) until term.
