During pregnancy, expectant mothers eagerly anticipate hearing their baby's first heartbeat. Listening to the baby's heartbeat, expectant mothers can also feel a little life slowly taking shape in their belly. In addition, expectant mothers can also check the health of their fetus through the sound of their heartbeat. What does mild fetal tachycardia mean?
Fetal tachycardia refers to a fetal heartbeat exceeding 160 beats per minute. This situation usually occurs due to severe fetal hypoxia, but not all fetal heart abnormalities are caused by hypoxia. Some fetuses may have a rapid heartbeat due to the following reasons:
1. Fever: The condition of the pregnant woman also affects the changes in fetal heart rate. If the pregnant woman has a fever, the fetal heart rate often exceeds 160 beats per minute.
2. Hyperthyroidism: Pregnant women with hyperthyroidism have a very fast heart rate, and the fetal heart rate often exceeds 160 beats per minute.
3. Medication: If pregnant women take certain medications, such as salbutamol for premature birth or atropine, it can cause an increase in heart rate in both mother and baby.
4. Umbilical cord entanglement: In addition, in the presence of umbilical cord entanglement, due to fetal movement, the entanglement may sometimes worsen, and the fetal heart rate will continue to accelerate. If this situation occurs before 36 weeks, due to the small size of the fetus, it can move freely in the uterus, and this entanglement can be transient; If it occurs after 36 weeks, due to the fixed position of the fetus, this entanglement can cause fetal distress or even death.
So, once mothers discover that their fetus's heartbeat is too fast, they must seek medical attention promptly and monitor the fetus's heartbeat at all times.
