Understanding Fetal Monitoring and Bradycardia in Operative Reports

Question
I am a medical transcriptionist working from home on an operative report.  This woman had arrest of descent ... at complete/complete 0 station (?).  I have not heard of this.  Also, they hooked up (what sounds like) the "fetal scapley" to the monitor, where they noticed it was at 120s.  Hoping you can shed some light on this...

Answer
An arrest of descent at 0 station is common. If there is no further descent in 2 hours, a cesarean section is often the method of delivery. Often, an extermal heart monitor (belt around the fundus) is inaccurate and a "fetal scalp electrode is attached to the baby's head. This gives a more accurate reading.
