Antepartal analysis of fetal heart rate variability by abdominal electrocardiography.
The success rate of some methodological factors influencing the antepartal analysis of fetal heart rate variability (FHRV) by abdominal electrocardiography (aFECG) were studied in 80 normal and 554 high risk pregnancies. The success rate of FHRV analysis was found to be dependent on the gestational age with virtually 100% success at 22 to 25 weeks and at 40 to 41 weeks of gestation. The lowest ...
متن کاملQuantification of fetal heart rate variability by abdominal electro - 7 ( 1979 ) 27 cardiography
As fetal electronic monitoring has become a routine practice in modern obstetric units, rapid and accurate Interpretation of the cardiotocograph tracings has become important. Decreased fetal heart rate (FHR) variability is the most constant finding observed in severe fetal distress in the ante partum period. An experienced obstetrician, if acquainted with electronic monitoring, can recognize t...
متن کاملFetal electrocardiography: feasibility of long-term fetal heart rate recordings.
The feasibility and accuracy of long-term transabdominal fetal electrocardiogram (fECG) recordings throughout pregnancy were studied using a portable fECG monitor. Fifteen-hour recordings of fetal heart rate (FHR) were performed in 150 pregnant women at 20-40 weeks of gestation and 1-hour recordings were performed in 22 women in labour and compared with simultaneous scalp electrode recordings. ...
متن کاملVariations on fetal heart rate variability
Intrapartum electronic fetal monitoring (EFM) is widely used throughout the developed and developing world. This practice is based on the understanding that fetal heart rate (FHR) is sensitive to hypoxia. During labour, the fetus may be exposed to acute hypoxia during uterine contractions or intrapartum insults, and has well-established cardiovascular compensatory defence mechanisms, which idea...
متن کاملFetal Heart Rate Variability Extraction by Frequency Tracking
In this work, we propose an algorithm to extract the fetal heart rate variability from an ECG measured from the mother abdomen. The algorithm consists of two methods: a separation algorithm based on second-order statistics that extracts the desired signal in one shot through the data, and a hearth instantaneous frequency (HIF) estimator. The HIF algorithm is used to extract the mother heart rat...
