Comment
This case shows a good fetal reaction when FSE is applied, thereafter you see clearly the fetus Baseline Heart Rate. Between 23:12–23:50 it is hard to decide the Baseline Heart Rate, are there accelerations or decelerations ? The physician in this case interpreted the decelerations as early decelerations and a present Normal CTG trace.
