Fetal heart monitoring is still necessary after an ultrasound.
Ultrasound and fetal heart monitoring are two different tests that are used to assess the development of the fetus; these two tests cannot replace each other but can be used to complement each other.
Ultrasound uses ultrasound waves to check the general body structure of the fetus for any deformities or abnormalities. The amount of amniotic fluid, the condition of the placenta, the blood flow in the umbilical artery and the fetal heart rate can be seen under ultrasound. However, ultrasound can only observe the performance of the fetus at a certain moment in time, and does not allow for continuous monitoring.
Fetal heart rate monitoring, on the other hand, refers to the continuous monitoring of the fetal heart rate to determine the changes in the fetal heart rate in the uterus, and then to determine whether it is hypoxia, with continuity, and can be seen when there is a contraction of the fetal heart rate changes.
