Fetal anemia and heart rate patterns.
A retrospective survey was performed of the clinical records and cardiotocograms (CTG) of fetuses born in 1978 and 1979 at Helsinki University Central Hospital with hemoglobin concentration less than 170 g/liter in peripheral blood or umbilical artery. Eighty-three fetuses (0.7%) had thus defined anemia. Thirty-eight of them had late decelerations, 29 silent and nine sinusoidal fetal heart rate...
متن کاملFetal heart rate patterns during forceps operation.
It is currently taught that early decelerations, or type l Dip, are related to the compression of the fetal head in the birth canal, late decelerations, or type 2 Dip, to placental insufficiency and variable decelerations to cord compression. All these patterns are elicited by, and by definition related to, the uterine contractions. With the increasing use of electronic fetal heart rate monitor...
متن کاملProspective study of fetal heart rate and rhythm patterns.
The fetal heart beat, detected by ultrasound, was recorded for five minutes from 934 antenatal women--266 at 30 to 35 weeks' gestation and 718 at 36 to 41 weeks. Episodes of bradycardia < 100/minute ranging from 5-30 seconds' duration occurred in 3 (1.1%) of the former and in 9 (1.3%) of the latter group. Tachycardia > 180/minute ranging from 30-90 seconds' duration occurred in 1 (0.4%) of the ...
متن کاملDetection rate of fetal distress using contraction-dependent fetal heart rate variability analysis.
OBJECTIVE Monitoring of the fetal condition during labor is currently performed by cardiotocograpy (CTG). Despite the use of CTG in clinical practice, CTG interpretation suffers from a high inter- and intra-observer variability and a low specificity. In addition to CTG, analysis of fetal heart rate variability (HRV) has been shown to provide information on fetal distress. However, fetal HRV can...
متن کاملFetal acidemia and electronic fetal heart rate patterns: is there evidence of an association?
OBJECTIVE Despite the ubiquity of electronic fetal monitoring, the validity of the relationship between various fetal heart rate (FHR) patterns and fetal acidemia has not yet been established in a large unselected series of consecutive pregnancies. The aim of this study was to examine the published literature for evidence of such a relationship. METHODS Four hypotheses based on assumptions in...
