Since you know you are pregnant, one of the first milestones you may already eagerly been waiting for is to hear the thump, thump of your baby's heartbeat. This is one of the most convincing voice there. And although it may sound the same to you from examination to examination, no major changes occur in the heart and circulatory system every week!
Although at that sweet, sweet heart rate has not yet arrived, the different blood vessels has been formed in the embryo, which will soon develop into your baby's heart and circulatory (blood) system. In the early stages, the heart is like a tube that twists and divide, eventually forming the heart and valves (which open and close to let blood from the heart to the body). In fact, at week 5, the tube heart began to beat spontaneously, even though you can not hear it. During the first few weeks, blood vessel precursors also began to form in the embryo
By 6 weeks, your baby's heart -. Now beats 110 times per minute - has four hollow spaces, each with its own entrance and exit to allow blood to flow in and out of each chamber. In just two weeks, that number will increase to 150-170 beats per minute. That's about twice as fast as yours!
With all this growth, a strong possibility that you will be able to hear your baby's heartbeat for the first time about a week 9 or 10 weeks of pregnancy. It will be about 170 beats per minute at the moment, the level of which will slow from here on out. Your doctor or midwife will put a handheld ultrasound device called a Doppler in your stomach to amplify signals.
Can not hear it yet? Dont worry. It just means that the shy guy or gal hiding in the corner of the uterus or have his back facing out, making it difficult to Doppler to find the target. In a few weeks (or on a subsequent visit), magical sound of your baby's heartbeat will definitely be heard for your listening pleasure. And the doctor will check to make sure everything is fine, so feel free to ask questions if you are concerned.
Some time between 6 weeks and 9 weeks of pregnancy, your doctor (and / or a trained sonographer) will conduct your first trimester ultrasound. This will not only ensure your pregnancy and (along with how many babies you are carrying and placement of the fetus) but also check that the heart is beating.
During the ultrasound the second trimester, or, your doctor will examine the structure of the baby and whether the problem (known as can be detected. About 36,000 babies (or 9 out of every 1,000 babies) are born each year with congenital heart defects, making this type of general partial interruption major birth. Although there is no cure for heart defects in utero, and some defects can not be detected until after birth, diagnosis during pregnancy helps doctors decide where to give your baby (usually at a medical center that is great , in which the child heart care provided immediately after birth). Sometimes these problems should be treated with surgery right after birth, while the other disabilities may need to be repaired at an older age or treated with medication. If doctors detect heart rhythm problems fetus, he may prescribe medication to decrease the likelihood that your baby will be born early.
The good news is that sebag ian major congenital heart defects can be repaired and managed if detected early and treated promptly. Children with congenital heart disease needs to visit a cardiologist regularly during the period and their adult lives.
circulatory Exciting developments continue at 12 weeks, when the baby-to-be get busy bone marrow to produce blood cells. By 17 weeks, begin to regulate heartbeat in preparation to support the baby in the outside world. (Up to this point, the heart has been beating spontaneously.) In three weeks, about 20 weeks you can hear your baby's heartbeat with a stethoscope.
If you need a better doc listen (and view), he may recommend that you get a fetal echocardiogram, a special ultrasound evaluation of the fetal heart, between 18 and 24 weeks. (If you have a family history of congenital heart defects, or if you personally have diabetes, phenylketonuria or autoimmune disease, make sure you get one.)
Now, the baby's heart beats about 140 times per minute. At the close of week 25, the capillaries (the smallest blood vessels) are forming and filling with blood. capillary movesoxygenated blood through the coronary arteries to tissues throughout the body of the baby and then eat deoxygenated blood back to the lungs -. This makes the tiny blood vessels-the main components of the circulatory system
baby's circulatory system would continue slowly and continues to grow, so that by 40 weeks was ready to debut outside the womb.
While the circulatory system rapidly developing fetus during pregnancy, it's really quite different functions in the womb than it does after the baby is born. Before birth, a baby's lungs is not functioning, because the baby was not breathing in the womb. Until your baby is born and took their first independent breath, she developed circulatory system depends on the umbilical cord blood to supply oxygen and nutrient-rich. the umbilical artery and vein transport what baby needs from you to him, then brought unoxygenated blood and waste products back to you for deletion
Some other differences :. The fetal heart has three shunt - or shortcut - that direct blood away from the lungs (because they simply are not needed in the uterus) and liver. Just like you, your baby has a pulmonary artery (carrying blood from the heart to the lungs) and the aorta (carrying blood from the heart to the body). Yet another is related by blood vessel (ductus arteriosus), which also serves to shunt blood from the lungs in the womb. Finally, the child has to-the-womb only opening between the upper chamber of the heart (patent foramen ovale), which again shunting blood from the lungs.
After the baby is born, all differences disappear entirely fetus (or starts to go). When the cord is cut, the baby's lungs take in air, fetal circulation system is switched off, the shunt started to close. And all systems go for the baby.
Many of the developing and changing when your baby is in the womb. While certain things out of your control that can affect the development of your baby's heart - such as genetic disorders - there are steps you can take to help ensure the ticker of your baby as healthy as possible:
