The fetal heart rate usually appears around 7 weeks of pregnancy. If it has not appeared after repeated examinations beyond 7 weeks, it may be due to fetal arrest. So, how long after fetal arrest can the fetal heart rate not be measured?
After fetal stop, the pregnancy reaction of the pregnant woman will disappear, and the fetal heart rate will also disappear. Generally, fetal heart rate cannot be measured shortly after fetal stop. There are many reasons for fetal stop, most of which are caused by abnormal embryonic development in early pregnancy. However, due to the different physical conditions of each pregnant woman, the time of fetal stop is also different, and it is difficult to determine fetal stop solely based on one's own perception. Therefore, pregnant women should undergo regular prenatal check ups in order to detect fetal stop early.
Pregnant women should avoid drug abuse, alcohol abuse, smoking, and exposure to harmful radiation during pregnancy, as these situations can cause fetal arrest. Therefore, pregnant women need to pay more attention. If a pregnant woman has a cold or other illness during pregnancy, if it is not serious, she can improve it by adjusting her diet and daily routine, which can avoid taking medication and reduce its side effects.
During pregnancy, if a prenatal check-up shows the presence of fetal sprouts but no fetal heart rate, it may also be a sign of fetal arrest. Pregnant women can go to the hospital for further examination later. If the test results are still the same, it can be confirmed that the pregnancy has stopped.
