The fetal heart monitoring during pregnancy is important to ensure the health and well-being of the unborn baby. A normal fetal heart rate ranges from 120 to 160 beats per minute， and a heart rate of 165 is slightly above the upper limit of this range. However， this does not necessarily indicate any cause for concern， as fetal heart rate can vary throughout the pregnancy.
Various factors can influence fetal heart rate， including the activity level of the fetus， maternal medication， maternal emotions or stress， and the gestational age of the baby. For example， the fetal heart rate tends to increase during fetal movement or maternal contractions， which means that a heart rate of 165 could be a normal variation in response to fetal activity.
It is recommended that pregnant women receive regular prenatal care， including fetal heart monitoring， to ensure the optimal development of their babies. If any abnormalities are found during monitoring， such as a consistently high or low fetal heart rate or signs of fetal distress， further testing or interventions may be required.
In conclusion， a fetal heart rate of 165 may be considered within the normal range but should be monitored closely by healthcare professionals. It is important for pregnant women to follow their doctor's advice and stay informed about their baby's health throughout their pregnancy.
