What are the causes of heart murmurs in newborn babies?

I don’t know what the cause is, but in recent years many newborn babies have had heart problems. Why is this? Why are newborn babies prone to heart problems? This is an issue that many parents are concerned about and take very seriously. What are the causes of heart murmurs in newborn babies? Let us take a look at what causes this disease. A bright future for my child. Let parents rest assured!

1. Doctors may hear heart murmurs in some children during physical examinations. Many parents think their children have heart problems, so they take their children to seek medical treatment blindly. In fact, the murmur is caused by the enhanced vibration of blood flow in the pulmonary artery. The murmur produced by this vibration is high-pitched and soft, but generally does not exceed level II and is not conducted.

2. Heart murmurs are generally more obvious when children have a fever, cry, or exercise vigorously, and weaken when they are quiet. This kind of heart murmur is not a heart disease. We call it a "functional murmur" or "harmless murmur", which will not affect the child's growth and development. Physiological murmurs in children usually first appear in infancy, increase in number in children aged 2 to 3 years old, and are most common in children aged 3 to 7 years old.

3. The growth and development of children with congenital heart disease are different from those of normal children. Some of them will have palpitations and shortness of breath when they move a little, and some will suffer from lack of oxygen and cyanosis. If you find your child has a heart murmur, parents should not be overly nervous, otherwise it will cause some mental and psychological burden on the child. You should take the child to the hospital for examination.

Every child has a different physique, which means that some children have weak constitutions and poor resistance. Some children have good physique and strong resistance. Plus, every child's heart is different. Some children have heart murmurs when they cry, which are the functional murmurs mentioned above. Some children do have heart problems, which may be caused by congenital heart disease, and this requires proper treatment. These are the reasons why newborn babies have heart murmurs.
