Why are there symptoms of fetal arrest in late pregnancy?

Fetal arrest symptoms generally occur during the first three months of pregnancy. Fetal arrest in the late stages of pregnancy is considered to be related to abnormal symptoms such as fetal umbilical cord around the neck or umbilical cord knot. If the examination finds fetal arrest, be sure to promptly follow the doctor's advice to do B ultrasound and other related examinations to clarify the specific cause of fetal arrest, and then follow the doctor's advice for treatment.
