Fetal movement jumps like a pulse, this situation is a normal pregnancy reaction, may also be fetal distress, umbilical cord around the neck and other causes of abnormal fetal movement, need to pay attention to, if necessary, consult a doctor to find out the cause of the disease. 1, normal phenomenon: fetal movement is a subjective feeling, most primigravid women in 18-20 weeks of pregnancy can feel the fetal movement, to 29-38 weeks to reach the peak, fetal movement at night and in the afternoon is more active, there can be a jump like a pulse. If the fetal movement is regular, and the number of times in the normal range, it means that the fetal development is normal. 2、Pathological factors: (1) Fetal distress: caused by insufficient oxygen in maternal blood and obstacles in oxygen transportation and exchange between mother and fetus, frequent fetal movements may occur in the early stage of hypoxia, which may appear like pulsation, and then may gradually weaken or decrease in number, and then disappear, and in serious cases, the life of the fetus may be endangered. (2) Umbilical cord around the neck: the umbilical cord is wrapped around the baby’s neck. When the umbilical cord is wrapped too tightly, it can lead to the obstruction of blood circulation of the fetus, resulting in ischemia, hypoxia, and frequent fetal movements, which gradually change and slow down. If there is a situation where the fetal movement is like a pulse, the rhythm and number of fetal movements should be closely observed. Once abnormalities are found, it is necessary to go to the Obstetrics and Gynecology Department in time and undergo further examination to clarify the cause of the disease, and if necessary, the doctor will carry out the appropriate treatment.
