Patient's question:
Here is the English translation of your text, with the line breaks preserved as instructed:---
Not long ago, I had a fetal heart monitoring test. Some doctors said there were no problems, while others said the fetal heart rate was too fast and recommended oxygen therapy, twice a day. I'm now worried about any potential impact on the baby. Could you please tell me what the line below the fetal heart monitoring is?
---
Doctor's answer:
During fetal heart monitoring, the top line represents the fetal heart rate, which shows normal variation and no change in direction. The bottom line represents uterine contractions. You should primarily observe for any conscious abdominal pain. If there is none, you can focus on carefully monitoring the fetal movements, as increased walking or other activities in the later stages of pregnancy may cause recurrent abdominal contractions. If conscious abdominal pain reappears, this requires hospitalization.
