Introduction to the heart structure and function
Hello, we are together today to learn about the structure and functioning of the heart and about the related elements of pre-cardiatric disease. First, let’s look at the structure of the heart. The heart is mainly a very important organ made up of muscle composition, which is similar in size to our fists, on the center left of the chest cavity. It consists mainly of two cardions, two cardiovasculars, four valves and two large vascular groups. Its function is similar to that of a fuel truck ‘ s engine, maintaining the blood cycle, transporting nutrients to the whole body, and taking metabolic waste away is one of the most important organs of the human body.
ii. What is the preconception (incidence and cause of illness)
Preconception, which we call congenital heart disease, is usually referred to as pre-heart disease by abbreviation of professional terminology. The incidence of congenital diseases is still high, and according to statistics it is about 8-10 per 1,000. What’s the concept? This means that 8 to 10 births per 1,000 live births are pre-existing, which is still higher. A lot of parents would ask, why do you have to be sick? Actually, the cause is not very clear. We can be broadly divided into two broad categories, the first is internal and the second is external. Internal factors refer mainly to the anomalies of genetic material, the most serious of which are those of chromosomes. For example, like 21-triple syndrome, what we call Down Syndrome and Down Baby, children are particularly vulnerable to a combination of preconceptions, with a 50 per cent chance of combining preconceptions. What’s the external factor? For example, mother ‘ s infection, intrauterine infections, and uterine infections in the early stages of pregnancy have a particularly high impact, as rubella virus infections can cause heart defects. Radiation, as we all know, exposure to ionizing radiation during pregnancy and filming can lead to foetal malformations. Then poisoning, like drugs or food. Other things include metabolic anomalies, metabolic anomalies in sugar, metabolic anomalies in amino acids, metabolic anomalies in fat, etc., which can also cause heart abnormalities.
III. Types of preconceptions (left-right diversion, right-left diversion, no-segregation symptoms)
What are the types of preconceptions? We usually classify on the basis of whether there is an abnormal diversion of a prior heart disease, broadly divided into three categories: left-to-right, right-to-left and no-diversion. The most common type is left-to-right diversion. What is the concept? Blood in the left cardiac cavity is diverted to the right cardiac cavity, with common loss of room spacing, loss of room spacing and unsealed artery catheters. Right-to-left diversion refers to the right blood being diverted to the left, low-oxygen blood being mixed into high-oxygen blood and then transported to the whole body, a type that tends to be violet, and left-to-right diversions do not occur early in the disease. This type of disease is relatively common in Faro Quad. Non-continental pre-cardiatric diseases, including narrow pulmonary artery valves, narrow aortic valves, narrow aortic arteries, etc.
IV. What are the signs of premeditation? How do we know this kid’s not premeditated?
Clinical performance for pre-cardiac diseases varies very widely, with minor conditions and no symptoms. The severity of the condition also varies according to the type of preconception, and the degree of severity. We know that a serious arrhythmia, a right-left diversion, has a violet. Like the lips, the fingers and the colours of the purple twigs, you can also have a twirl. Secondly, the endurance of activities is affected, and when newborns and infants are small, they suffer from a lack of milk and a little rest. A little older, the endurance of the movement is affected, the movement is restricted. Thirdly, breathing is fast and difficult, and some children are free of pneumonia, and can feel breathing more and more quickly than normal children, which is one of the effects of pre-heart diseases. Fourth, growth and growth are slow, and some children eat a lot, but they don’t grow meat, weight and height are affected. And what’s the more common expression? In particular, children suffering from pre-heat diseases in the left-right diversion are particularly sweaty, and the greater the flow, the more sweaty. These manifestations, no speciality. But when there are these anomalies, we need to be vigilant. It would be better to go to a specialist hospital, to find a specialist, to remove pre-conceptions. Early detection, early intervention, and this is more beneficial for the growth and development of the infected child and for post-natal planning.
