Cardiac Troponin T Levels of Umbilical Cord in Neonates with Abnormal Fetal Heart Rate
OBJECTIVE Most neonatal encephalopathic disorders appear to be caused by perinatal events. Persistent myocardial ischemia leads to cellular necrosis and release of troponin from cardiac muscles. Fetal distress during labor may be detected by monitoring the fetal heart rate. However little is known about the relationship, if any, that exists between fetal heart rate abnormalities and the fetal c...
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 کاملDifferentiating haematoma with the R2' relaxation rate
Introduction Subdural haematoma (SDH) is a form of traumatic brain injury that can be classified as acute, subacute or chronic, based upon time from injury. When acute, it is a medical emergency in which surgical decompression is the only option to prevent mortality. Small subdurals and those that are no longer actively bleeding may be left to re-absorb spontaneously and clinical decision-makin...
