Is the fetal heart rate higher than 150 a girl? Is fetal heart rate accurate according to fetal sex?

In fact, boys and girls are the same, but there are still many people who especially want to know the baby's gender and prepare clothes and gifts for the baby. So are girls with a fetal heart rate higher than 150?

What is fetal heart rate? Fetal heart rate means that the fetal heart rate is regulated by sympathetic and parasympathetic nerves. By recording the instantaneous change of fetal heart rate, we can understand the reaction of fetal heart rate during fetal movement and contraction, so as to judge whether the fetus is hypoxic.

How does the fetal heart rate change? Normal fetal heart rate is between 120- 160 beats/min. In the fifth week of pregnancy, the fetal heart rate is close to the maternal heart rate, which is 80-85 beats/min. In the ninth week of pregnancy, the heart rate accelerated to 170-200 beats/min, and gradually slowed down to 65400 beats in the second trimester.

Is the fetal heart rate 150 above a girl? Not necessarily.

There is no scientific basis for looking at gender through fetal heart rate. Listening to the fetal heart rate is mainly to understand the fetal heart rate response during fetal movement and contraction, so as to judge whether the baby in the abdomen is hypoxic.

There is a folk saying that the fetal heart rate is lower than 140 beats/min for boys and higher than 140 beats/min for girls. In fact, the heart rate of female baby is higher than that of male baby, but it is right at birth. There is no difference in heart rate between male and female babies.

Fetal heart rate depends on sex. number

The normal fetal heart rate is between 120- 160 beats/min, but in fact, the rate of fetal heart rate has nothing to do with sex, and it will only change with the gestational age.

The speed of fetal heart rate is only related to the gestational age and the activities between fetus and mother. There is no difference between a baby boy and a baby girl. When taking a B-ultrasound, the baby's activity is a little higher and the fetal heart rate is a little higher. Anyway, the baby's activity is not large, and the fetal heart rate will be slightly lower.

What is the relationship between abnormal fetal heart rate and fetal heart rate monitoring? If the fetal heart rate lasts for more than ten minutes, less than 1 10/min, or more than 160/min, it means that the fetal heart rate is abnormal, or the heartbeat is irregular, fast and slow, jumping around and stopping. In most cases, it means that the fetus lacks oxygen in the uterus. The more serious the abnormality, the more serious the hypoxia. But not all fetal heart abnormalities are caused by hypoxia.

If the fetal heart rate is lower than 120 beats/min or higher than 160 beats/min, the fetal heart rate pattern is abnormal and the fetal heartbeat is irregular, which is mostly related to intrauterine hypoxia. It may also be the physical influence of pregnant women. For example, pregnant women have a fever, the fetal heart rate often exceeds 160 times/minute, and pregnant women have hyperthyroidism. If you take some drugs during pregnancy, the drugs will act on the fetus through the placenta, which will also lead to the slow heart rate of the fetus.

How long does it take to hear the fetal heart? Pregnant mothers can count fetal heart rate with Doppler stethoscope. Pregnant 12 weeks, you can hear the fetal heart with wine. Pay attention to listening in a quiet environment, but if you use an ordinary stethoscope, it will take 18 weeks to hear.

The order of how to monitor the fetal heart is from the lower left and lower right of the abdomen, then to the upper left and lower right, and then to the middle left and right. 100- 120 beats/min is mild bradycardia, and 160- 180 beats/min is mild tachycardia.

Generally speaking, fetal heart sounds are the loudest in the abdominal wall of pregnant women with the fetus facing backward, and the loudest heart sounds are different with different fetal head positions.

When monitoring fetal heart rate, we should pay attention to the regularity and flawless sound of normal fetal heart rate. When there is fetal movement, the fetal heart rate will be slightly faster. If there is no fetal movement, the fetal heartbeat exceeds 160 beats per minute, or is lower than 120 beats, or the heartbeat is irregular and intermittent, indicating abnormality.
