In brief: Fast/slow/none

Assessing the fetal heart is a bit problematic.
Since they are isolated inside the bag of waters, we are limited to detecting rate as fast/ slow/ normal or none. Various factors can lead to various rate changes. The fetal heart is usually beating much fast ; 130-160/min are routine. Stress can speed or slow the rate. When checking newborns, I have never had one with fibrillation in 3 decades.
