Maternal and fetal heartbeat couplings are evident throughout development. Most of the published work, however, did not consider maternal physiological factors such as Heart Rate Variability (HRV), investigate interrelationships maternal-fetal coupling parameters. The aims this study to whether: 1) (HR) ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3....

conclusions overall, incidence of birth trauma in kashan city was lower in comparison with most studies. considering existing risk factors, further monitoring on labor, and delivery management in teaching hospitals are recommended to prevent birth injuries. in addition, careful supervision on students and residents' training should be applied in teaching hospitals. patients and methods in this ...

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 presentation. During the acupoint stimulation (20 min, two times a week), the women were submitted to computerized non-stress test. Fourteen cases were tr...

Gross fetal movement was detected using a lower frequency ultrasonic Doppler shift than that used in the study of fetal heart action. The movement signal was changed into deflection which was recorded on CTG chart simultaneously with the fetal heart rate (FHR), and was called the fetal actocardiogram. Visual analysis of the actocardiogram showed bursts of active fetal movements in the active fe...

Evidence of the short term relationship between maternal and fetal heart rates has been found in previous studies. However there is still limited knowledge about underlying mechanisms and patterns of the coupling throughout gestation. In this study, Transfer Entropy (TE) was used to quantify directed interactions between maternal and fetal heart rates at various time delays and gestational ages...

Antepartum cardiotocography (CTG) is the most frequently used method for fetal surveillance during labor. In highrisk-pregnancies antepartum fetal heart rate assessment can be used to predict fetal compromise. However, the false-positive rate can be as high as 60 % for various reasons. Higher sensitivity might be achieved either by longer recording (fetal deep sleep phase) or by adding ultrasou...

CTG monitoring of the fetal heart rate and uterine contractions during pregnancy and delivery provide information on the physiological condition of the fetus needed to identify hypoxia. Interpretation, however, requires experience and important patterns might be missed or misinterpreted due to stress, exhaustion or distraction. Interpretation has also been reported subjective with poor reproduc...

OBJECTIVES The aims were to evaluate whether any changes in blood flow in fetal inferior vena cava (IVC) are observed during Atosiban tocolysis within the first 48 hours of therapy. METHODS Detailed Doppler evaluation of blood flow in fetal IVC was performed prior to Atosiban administration and after 24 and 48 hours respectively. Maternal and fetal heart rate was assessed. IVC Doppler indices...
