Fetal movement normal fetal heart rate is low is occasionally occurring is generally a normal phenomenon, lasting 10 minutes or even longer time fetal heart rate is low, may be the performance of intrauterine fetal hypoxia.
1. Normal fetal movement is 3~5 times in an hour, 30~40 times in 12 hours, the fetal heart rate is normal at 110~160 times/minute, the fetal heart rate is lower than 110 times/minute as the fetal heart rate is low.
Fetal heart rate can understand the value of fetal heart rate through fetal heart monitoring, the value of fetal heart rate is not static, each measurement will be different, fetal heart rate is lower than 110 beats/minute for a short period of time is a normal phenomenon, it may be the fetus itself sinus bradycardia, the mother taking some drugs, such as propranolol caused.
2. If the fetal heart rate is lower than 110 beats/min for more than 10 minutes or even longer, it is considered to be caused by intrauterine hypoxia, such as placental dysfunction, umbilical cord torsion, umbilical cord kinking, etc. The causes of low fetal heart rate are more common.
There are many reasons for low fetal heart rate, so further examination is needed to understand the abnormality, and then targeted treatment.
