Patient's question:
My cousin is 27 years old this year. She recently just got pregnant, and since it's the first child in the family, everyone pays great attention. During her prenatal check-up this time, she was told that there was a variation in the fetal heart rate amplitude. She is very worried and scared about what it might mean for the child. She wants to ask what the variation in fetal heart rate amplitude means?Doctor's answer:
This is the indicator for measuring fetal heart rate. The baseline fetal heart rate should be within the range of 120 bpm to 160 bpm. The amplitude variation should be the range from the maximum value exceeding the limit to the baseline value. The amplitude variation should be between 6-25 bpm, which reflects the fluctuations around the baseline rate. This can be used as a reference to assess the condition of fetal heart monitoring. It is recommended that you judge whether there is fetal distress based on the score of the fetal heart monitoring.
