Fetal heart monitoring is a widely used obstetrical aid in the prenatal and labor period. Fetal heart rate monitoring mainly includes the baseline of the fetal heart rate, the acceleration of the variation of the baseline, and contractions, etc., and through the comprehensive analysis of these conditions to assess the intrauterine development of the fetus, whether there is hypoxia.
