The inner child of a pregnant mother is very important. The child is the baby in every mother's heart. Children decide their mother's future. Everyone knows that a person needs a heart to live. The same is true for the fetus. Although the fetus' heart is very weak, it is still a heart. So, at what weeks of pregnancy can the fetal heart rate and fetal bud be measured? 1. How many weeks of pregnancy can the embryo and fetal heart be detected? Characteristics of the embryo bud and fetal heart. The first month of pregnancy is the embryonic bud and fetal heart stage, and the growth rate of the new life during this period is the fastest in its life. On the second week of pregnancy, about 4 days after fertilization, the sperm and egg, which have broken down into a cell mass, travel along the bilateral fallopian tubes to the uterus. In the third week, the cell mass sheds its outer membrane in preparation for embryo implantation. In the fourth week, the blastocyst is firmly embedded in the uterus. At this stage, the prototypes of the fetal nervous system and circulatory organs (the formation of basic tissues) have basically appeared, and the liver has begun to develop significantly from this stage. The prototypes of the eyes and nose have not yet been transformed, but the prototypes of the mouth and jaw can be seen. The umbilical cord of the fetus connected to the pregnant mother also begins to grow from this stage. The first month of pregnancy is the embryonic bud and fetal heart stage, and the growth rate of the new life during this period is the fastest in its life. After the fusion of sperm and egg to form sperm-egg union, the embryo implants and the sperm-egg union gradually disintegrates into a multicellular fetal sac. After more than thirty days of pregnancy, each primitive cell begins to divide and gradually forms a fetal bud and fetal heartbeat, which further develops into a fetal heartbeat. This is the whole process of a fetus being born. At this time, blood signals of heart beats can be seen during B-ultrasound or B-ultrasound examination, and further development will lead to the birth of a fetus. Generally speaking, the fetal heartbeat will be detected during B-ultrasound at around 8-10 weeks, but if the B-ultrasound is done too early, it will be difficult to see the gestational sac because it is too small. Under normal circumstances, it is easy to see clearly at 8-10 weeks of pregnancy, and if B-ultrasound is done too early, theoretically the surface will fluctuate to the point of being sensitive, and the newly formed test tube embryo will be detrimental to the embryonic development. It is best to avoid doing B-ultrasound too early. Normal fetal heart rate: The normal fetal heart rate is 120-160 beats/minute, regular and with moderate heights, like the "ticking" sound of a clock. When the fetus exercises, the fetal heart rate can increase by 10 to 20 beats per minute. If the normal and sustained rate is higher than 160 times/minute, or less than 110 times/minute, it is abnormal. |
