At that time, the fetal heart rate pattern
The normal or reactive fetal heart rate pattern
is characterized by a baseline frequency between 110 to 160 beats per minute, presence of periodic accelerations, a normal heart rate variability with a variability between 5 and 25 beats per minute and the absence of decelerations.7 If one or more of its parameter is abnormal, it is regarded as non-reactive trace.
Fetal acidemia and electronic fetal heart rate patterns
: is there evidence of an association?
Eight women had a nonreassuring fetal heart rate pattern
in group two, out of which five were due to uterine hyperstimulation and second stage decelerations.
Despite the fact that cCTG is widespread, its use is still thwarted because computer programs are considered inevitably based on the current, limited knowledge of fetal heart rate patterns
, in relationship to neonatal long-term outcome .
Considering the mode of delivery has no effect on perinatal outcome in the presence of normal fetal heart rate pattern
, it is recommended that cesarean section be performed in the face of abnormal FHR pattern and confirmed fetal acidosis by fetal scalp PH.
The fetal heart rate patterns
were classified as reassuring, suspicious and pathological according the Royal College of Obstetricians and Gynaecologists (RCOG) guidelines for fetal heart rate monitoring.
Furthermore, of 95 children with CP in the study, 78 had electronic fetal heart rate monitoring, and only 21 (0.19% of all those in the study) had a nonreassuring fetal heart rate pattern
are marked by a period of uncertainty for obstetricians, nurses, midwives, and parents over the well-being of the baby due to an abnormal fetal heart rate pattern
, possibly caused by a lack of oxygen.
Prolonged end-stage fetal heart rate pattern
For emergent transfer, the primary reason was nonreassuring fetal heart rate pattern
(0.5%) and postpartum hemorrhage (0.2%).
