The 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 کاملWhat is the “normal” fetal heart rate?
Aim. There is no consensus about the normal fetal heart rate. Current international guidelines recommend for the normal fetal heart rate (FHR) baseline different ranges of 110 to 150 beats per minute (bpm) or 110 to 160 bpm. We started with a precise definition of "normality" and performed a retrospective computerized analysis of electronically recorded FHR tracings. Methods. We analyzed all re...
متن کاملThe future of fetal heart rate monitoring.
Medical technology is developing at an accelerated rate. Advances and refinement in techniques of electronic fetal heart rate (FHR) monitoring are continually being designed and tested. Many of these show real promise for the future. Never-theless, for the next several years there are two major considerations. First, a more universal application of FHR monitoring i.e., to the "normal" patient ä...
