Normal heart rate of a 14-year-old girl

In fact, the heart rates of men and women are different, and the heart rates of normal people and children are also different. The age of 14 should be judged based on the normal heart rate. Most of them belong to the adolescent stage, which is no longer the heart rate of children. The normal average heart rate index for pregnant women, men, women, and the elderly all has different stage standards.

There are only two genders, so there is a 50% chance that you are correct if you say either one...

Experts say: Girls have a higher heart rate than boys, but this is only true when they are just born. There is no difference in the fetal heart rate between boys and girls. The speed of heart rate only varies with gestational age. At about 5 weeks of pregnancy, the fetus' heart rate is close to the mother's heart rate, which is 80 to 85 beats per minute. Then, during the 9th week of pregnancy, the heart rate gradually increases to 170~200 beats/minute. Then during the second trimester, the rate gradually slows down to 120-160 beats per minute.

There are some misconceptions:

Statement 1: If the fetal heart rate is less than 140 beats/minute, the fetus is a boy.

Myth 2: If the pregnant woman's abdomen is too protruding, it is a girl; if the abdomen is not too protruding or the lower abdomen is protruding, it is a boy.

Expert opinion: If a pregnant woman has a short upper body, the space for the fetus to develop can only extend outward, so the abdomen will appear large. On the contrary, if a pregnant woman has a long upper body, it can provide enough space for the fetus to grow, and the abdomen does not need to protrude outward.

Myth 3: If a pregnant woman has a lower abdomen (large lower abdomen), she is going to have a boy, and if she has an upper abdomen (large upper abdomen), she is going to have a girl.

Expert opinion: If the pregnant woman is carrying the upper part of the baby's belly, it may be her first pregnancy or she may have a good body shape. After a pregnant woman has been pregnant once, her abdominal muscles relax and will naturally "sag" when she becomes pregnant again.

Myth 4: Black nipples mean a boy

Experts say: Nipple color is affected by hormones in the body. The increase in progesterone and melanocyte-stimulating hormone levels during pregnancy causes certain originally dark areas on the body surface to become darker. The color will return to normal quickly after giving birth, and this phenomenon has nothing to do with the sex of the fetus.
