First Online 17 September. fever, chorioamnionitis, fetal acidemia, and labor intoler-ance have been linked to fetal tachycardia greater than bpm. Maternal tachycardia is defined as a baseline heart rate greater than bpm. Anxiety, a low-grade temperature elevation, fever, and chorioamnionitis have been associat-ed with an MHR between and bpm (Yamashiro.

If the fetal heart rate returns to normal, allow labour to proceed, but monitor the fetal heart rate very carefully and frequently. If possible, monitor with a CTG. If the fetal bradycardia persists, the fetus must be delivered as soon as possible, which will be by Caesarean section in most cases.   The fetal anomaly ultrasound only detects 65 to 81 % of the patients with congenital heart disease, making it the most common structural fetal anomaly of which a significant part is missed during prenatal life. Therefore, we need a reliable non-invasive diagnostic method which improves the predictive value for congenital heart diseases early in pregnancy.

A comparative assessment of an automated blood microprocessor for fetal blood pH measurements in the labour ward. Intrapartum fetal heart rate (FHR) monitoring is widely used to assess fetal well-being and is utilized in ∼85% of births in the USA (1).

Despite revision of the guide-lines for categorizing FHR and uterine contraction pat-terns (1,2) and the publication of a number of reports and guideline documents (3–6) very little has been writ-ten.

Although electronic fetal heart rate monitoring remains the most popular technique for fetal surveillance during labour, there is much concern about the ever rising Caesarean section rate, probably partly due to this practice.

Fetal blood sampling is still the gold standard when it comes to measuring fetal. Summary. The fetal heart rates (FHR) of women admitted in labour, or in early labour after induction, were screened for up to 60 min (average 17 min) using computerized numerical analysis.

During the 1st stage of labor, maternal heart rate and blood pressure and fetal heart rate should be checked continuously by electronic monitoring or intermittently by auscultation, usually with a portable Doppler ultrasound device (see fetal monitoring).

Perinat. Evaluation of maternal heart rate (MHR) variability provides useful information on the maternal-fetal clinical state. Electrocardiography (ECG) is the most accurate method to monitor MHR but it may not always be available, and pulse oximetry using photoplethysmography (PPG) can be an alternative.

In this study we compared ECG and PPG signals, obtained with conventional fetal. Continuous electronic fetal heart rate monitoring (EFM) is used in the vast majority of all labors in the United States.

With the use of EFM categories and definitions from the American College of Obstetricians and Gynecologists, the National Institutes of Health, and the Society for Maternal-Fetal Medicine, clinicians can now better define and communicate tracing assessments.

Fetal monitoring was invented by Doctors Alan Bradfield, Orvan Hess and Edward Hon.A refined (antepartal, non-invasive, beat-to-beat) version.

The idea behind fetal heart rate monitoring is to allow your care provider to see how your baby is coping during labour, and to identify potential problems ahead of time. Fetal monitoring has been used universally during labour since the invention of the electronic fetal monitor (EFM) in
