Variability analysis of fetal heart rate signals as obtained from abdominal electrocardiographic recordings.
The present paper introduces an original method of digital signal processing for an automatic analysis of non-invasive abdominal ECG recordings on pregnant women starting from the 25th week of gestation. The procedure has been implemented on a DEC-VAX 750 digital computer at the Department of Electrical Engineering, Polytechnic of Milano and the signals are recorded at the Department of Obstetr...
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 کاملThe Effects of Maternal Opium Abuse on Fetal Heart Rate using Non-Stress Test
Background: Opium is one of the most commonly abused opiates in developing countries including Iran. Considering the importance of maternal health on the newborn, we aimed to assess the effect of opium abuse on fetal heart rate (FHR) characteristics in a sample of pregnant women in Zahedan, Southeast Iran.Methods: This cross-sectional study was done on 100 pregnant women referring to Ali-Ibn-Ab...
