Monitoring Fetal Movement and Heart Rate: What to Watch For in Late Pregnancy

Fetal movement and fetal heartbeat?

Hello Dr.
Lu: Around 34 weeks of pregnancy (on October 21), I noticed a sudden decrease in fetal movement.
On October 24, I went to the hospital to consult my attending physician for further monitoring of fetal movement and placental function.
The examination reports were normal, but there was indeed a noticeable decrease in fetal movement.
The attending physician could not determine the cause of the reduced fetal movement and recommended follow-up visits every three days to monitor placental function.
During my follow-up on October 26, fetal movement returned to normal, so I did not continue with the three-day follow-up visits.
I am currently at 35 weeks and 3 days of pregnancy, and in the past few days, I have observed a significant decrease in the frequency of fetal movements, and the strength of the movements has also noticeably diminished.
The fetal heart rate measured at least around 120 beats per minute, and at times even exceeded 170 beats per minute.
Given these circumstances, what should I be paying attention to at this moment?

There are several situations that can lead to decreased fetal movement, such as placental insufficiency, high blood pressure, reduced amniotic fluid, the mother being too busy or fatigued, and irregular meal times, among others.
Sometimes, the cause may not be identifiable.
It is recommended to ensure adequate rest, maintain a regular diet and schedule, limit sugary foods, stay well-hydrated, and monitor fetal movements daily.
If a blood pressure monitor is available at home, it is advisable to check blood pressure daily.
Please cooperate with your physician for regular prenatal check-ups and necessary examinations.
Sincerely, Dr.
Li-Cheng Lu, Taoyuan Hospital.

Monitoring fetal movement and heart rate during late pregnancy is crucial for assessing the well-being of the fetus. As you approach the final weeks of pregnancy, it is essential to be aware of the patterns of fetal movement and heart rate, as changes can indicate potential issues that may require medical attention.

Fetal movement is a significant indicator of fetal health. Typically, you should feel your baby move regularly throughout the day. A general guideline is to monitor fetal movements by counting how many times you feel your baby move in a two-hour period. If you notice a significant decrease in movement, it is essential to consult your healthcare provider. In your case, you mentioned that you experienced a decrease in fetal movement around 34 weeks and again at 35+3 weeks. While it is reassuring that the fetal heart rate remains within a normal range (120-170 beats per minute), the reduction in movement is something to take seriously.

The normal fetal heart rate typically ranges from 110 to 160 beats per minute, with variations depending on the baby's activity level. A heart rate above 160 beats per minute may indicate fetal distress, especially if accompanied by decreased movement. Conversely, a heart rate below 110 beats per minute can also be concerning. It is essential to monitor these changes and report them to your healthcare provider.

In your situation, since you have already experienced a decrease in fetal movement and have been advised to monitor your condition closely, here are some recommendations:
1. Daily Kick Counts: Continue to monitor your baby's movements daily. A common method is to count at least 10 movements within a two-hour period. If you notice fewer than 10 movements, or if the movements feel significantly weaker, contact your healthcare provider.

2. Hydration and Nutrition: Ensure you are well-hydrated and consuming a balanced diet. Sometimes, dehydration or low blood sugar can affect fetal movement.

3. Rest and Positioning: Sometimes, the position you are in can affect how you feel your baby's movements. Lying on your side can sometimes help you feel more movements.
4. Monitoring Heart Rate: If you have access to a fetal Doppler or heart rate monitor, you can use it to check the fetal heart rate at home. However, this should not replace professional medical advice. If you notice any significant changes in the heart rate, such as prolonged tachycardia (heart rate above 160) or bradycardia (heart rate below 110), seek medical attention immediately.

5. Follow-Up Appointments: Keep all scheduled follow-up appointments with your healthcare provider. If your doctor has recommended monitoring the placenta and fetal movements closely, adhere to that advice.
6. Know When to Seek Help: If you experience any other concerning symptoms, such as abdominal pain, bleeding, or a sudden decrease in fetal movement, do not hesitate to go to the hospital or contact your healthcare provider.

In conclusion, while it is reassuring that your fetal heart rate is within the normal range, the decrease in fetal movement is a concern that should not be overlooked. Regular monitoring, maintaining communication with your healthcare provider, and being aware of your body’s signals are crucial steps in ensuring the health and safety of both you and your baby as you approach delivery. Always trust your instincts; if something feels off, it is better to err on the side of caution and seek medical advice.
