When recording the fetal ECG using a scalp electrode and skin electrode placed on the mother’s thigh, it is only the fetal ECG signal that has sufficient strength to show the p-wave. If the maternal heart rate, i.e. ECG, is recorded the p-wave will not be visible in the recording.

2/9/2018 · The fetal scalp electrode allows a more continuous record of the fetal heart rate, which may be desirable where there is a concern about the well being of the fetus. Sometimes, even when the Doppler ultrasound can pick up the fetus’ heart rate, a fetal scalp electrode will be used to monitor the fetus’ cardiac function in more detail.
The incidence of scalp abscess after placement of a spiral fetal scalp electrode (i.e.
the type used since the early 1970s) ranged from 0.1% to 1.0% in retrospective studies of approximately 18,000 neonates. 46 Prospective studies have reported incidences between 0.6% 48 and 4.5%. 49. Reports of predisposing factors are conflicting.
A fetal scalp electrode is provided having a spiral tip 5 mounted on the distal end of a dielectric hub 4 and a reference electrode 9 mounted on the proximal end thereof. Conventional apparatus including drive tube ( 3 ) and guide tube ( 2 ) are used to attach the spiral tip to the fetal scalp in a cork screw fashion. These components are removed leaving electrode wires ( 8 ) connected to …
