How is fetal distress diagnosed? Fetal distress is diagnosed by reading the baby's heart rate. A slow heart rate, or unusual patterns in the heart rate, may signal fetal distress. Sometimes fetal distress is picked up when a doctor or midwife listens to the baby's heart during pregnancy.

Can you tell gender by the heartbeat?
An average fetal heart rate ranges from 110 to 160 beats per minute (bpm) and changes when the baby is active. Some babies have heart rates that are slower or faster than average. But this has nothing to do with the sex of your baby. “The fetal heart rate does not predict the sex of the baby,” says Dr.

What is the normal heart rate for a fetus?
If the heartbeat of the fetus is normal, chances of miscarriage are very low. A fetal heart rate range of 100-160 is considered as normal. If the baby’s heartbeat is not audible for a week or more, miscarriage is likely to happen. Unusually low or high FHR is one of the main fetal distress symptoms. Some placental or umbilical cord problems, excessive physical exertion by the mother, mental stress, genetic problems or any other complications can lead to low or high FHR in early pregnancy or in latter half of the pregnancy. FHR, as high as 180 or as low as 100 can be considered normal, as the average rate varies from fetus to fetus, and keeps on falling and rising during pregnancy. Mothers of different races may notice different heart rates as the rate of growth of the fetus may vary slightly, depending upon certain genetic factors. The way FHR is measured may change from country to country.
When does the heart rate of a fetus change?
The above chart describes how the heart rate of the fetus changes in the first and second trimesters. During the third trimester, it is comparatively stable. The FHR slows down slightly during the last (third) trimester before labor, but still, it is about twice the heart rate of an adult. In high risk pregnancies, FHR is monitored during labor.
How many trimesters are there in pregnancy?
As you know, pregnancy is divided into three trimesters. The miraculous journey of the fetus from week 1 to week 42 is divided into three stages for the sake of convenience. Depending upon the weight of the mom, position of the baby and location of the placenta, you can listen to baby’s heartbeats with the help of a stethoscope or fetoscope, at about 18-20 weeks, or even at about week 12. Using ultrasound technology, you can hear fetal heartbeats as early as 8 weeks. Baby’s heartbeat is also referred to as ‘fetal heart tone’ (FHT). Sometimes, the heartbeat is not audible until 12 – 14th week of pregnancy.
Why is FHR important?
So, FHR is used to estimate the age of the fetus. It is necessary for the mothers to know that the fetal heart rate varies naturally during movements of the mother. FHR measured while resting and FHR during other activities can be different. It is normal if you notice different rates at different periods of time, during a day.
What is low FHR?
