Fetal heart rate tracing interpretation in cases of fetal heart block: A
Simple assessment of FHR baseline variability can differentiate second
degree heart block (SHB) from complete heart block (CHB). In cases of
SHB, antepartum NST can be reliably used for fetal surveillance.
Intrapartum assessment of FHR variability as well as accelerations is
useful to select cases for safe vaginal delivery
