Apparatus for Continuous Monitoring of the Fetal Heart Rate *
APPARATUS FOR CONTINUOUS MONITORING OF THE FETAL HEART RATE.* By Edward H. Hon, Department of Obstetrics and Gynecology, Yale University School of Medicine. During the past four years continuous monitoring of fetal heart rate during labor and delivery has permitted the accumulation of accurate, permanent records which may be of value for the assessment of fetal heart rate as an index of fetal e...
متن کاملThe unreactive fetal heart rate.
The 'flat' fetal heart rate (FHR) trace both before and during labour is viewed ominously by many obstetricians and midwives. The current medicolegal climate relating especially to care in labour is such that much emphasis is placed on an unreactive FHR. There is a tendency to link an unreactive FHR with an adverse outcome. However, it is only in a minority of cases that this is true. Furthermo...
متن کاملImprovements in fetal heart rate analysis by the removal of maternal-fetal heart rate ambiguities
BACKGROUND Misinterpretation of the maternal heart rate (MHR) as fetal may lead to significant errors in fetal heart rate (FHR) interpretation. In this study we hypothesized that the removal of these MHR-FHR ambiguities would improve FHR analysis during the final hour of labor. METHODS Sixty-one MHR and FHR recordings were simultaneously acquired in the final hour of labor. Removal of MHR-FHR...
متن کاملExtraction of Fetal Heart Rate and Fetal Heart Rate Variability from Mother's ECG Signal
This paper describes a new method for extracting the fetal heart rate (fHR) and the fetal heart rate variability (fHRV) signal non-invasively using abdominal maternal electrocardiogram (mECG) recordings. The extraction is based on the fundamental frequency (Fourier’s) theorem. The fundamental frequency of the mother’s electrocardiogram signal (fo-m) is calculated directly from the abdominal sig...
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. ...
