Acceleration and Deceleration Capacity of Fetal Heart Rate in an In-Vivo Sheep Model
BACKGROUND Fetal heart rate (FHR) variability is an indirect index of fetal autonomic nervous system (ANS) integrity. FHR variability analysis in labor fails to detect early hypoxia and acidemia. Phase-rectified signal averaging (PRSA) is a new method of complex biological signals analysis that is more resistant to non-stationarities, signal loss and artifacts. It quantifies the average cardiac...
متن کاملThe intrapartum deceleration in center stage: a physiologic approach to the interpretation of fetal heart rate changes in labor.
One of the most distinctive features of fetal heart rate recordings in labor is the deceleration. In clinical practice, there has been much confusion about the types of decelerations and their significance. In the present review, we examined uteroplacental perfusion in labor, describe the pathophysiologic condition of decelerations, and explain some of the reasons behind the confusion about the...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
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 کاملA New Method to Derive Fetal Heart Rate from Maternal Abdominal Electrocardiogram: Monitoring Fetal Heart Rate during Cesarean Section
BACKGROUND Monitoring of fetal heart rate (FHR) is important during labor since it is a sensitive marker to obtain significant information about fetal condition. To take immediate response during cesarean section (CS), we noninvasively derive FHR from maternal abdominal ECG. METHODS We recruited 17 pregnant women delivered by elective cesarean section, with abdominal ECG obtained before and d...
