background: fetal heart rate (fhr) extracted from abdominal electrocardiogram (ecg) is a powerful non-invasive method in appropriately assessing the fetus well-being during pregnancy. despite significant advances in the field of electrocardiography, the analysis of fetal ecg (fecg) signal is considered a challenging issue which is mainly due to low signal to noise ratio (snr) of fecg. objective...

most fetal heart rate patterns can be interpreted accurately so that management decisions can be made correctly. how-ever, few fetal heart rate patterns are so ambiguous that the obstetricians cannot interpret them precisely. a 27-year-old woman at 38 weeks' gestation in her first pregnancy was admitted with heavy vaginal bleeding and decrease in fetal movements. fetal status was indeterminate ...

background: fetal electrocardiography is a developing field that provides valuable information on the fetal health during pregnancy. by early diagnosis and treatment of fetal heart problems, more survival chance is given to the infant. objective: here, we extract fetal ecg from maternal abdominal recordings and detect r-peaks in order to recognize fetal heart rate. on the next step, we find a b...

background: one of the first‑line assessment tools for fetal surveillance is nonstress test (nst), although it is limited by a high rate of false‑nonreactive results. this study was performed to investigate if external stimulation from vibroacoustic and halogen light could help in provoking fetal responsiveness and altering nst results. materials and methods: this is a clinical trial. sampling ...

background: relaxation-training, as an anxiety-reducer intervention, plays an important role in fetal health. the present study aimed to analyze the effect of maternal relaxation on stress test (nst), basal fetal heart rate, and number of fetal heart accelerations. methods: in this randomized controlled trial, 84 pregnant women were randomly divided into two groups of teaching relaxation and co...
