For those that are not easy to make clear, they can also make some auxiliary examinations, such as chest X-ray, ECG, B-mode ultrasound and heart fan scan. How does child heart have murmur to return a responsibility? Let's talk about it.
How does child heart have murmur to return a responsibility?
Some murmurs are signs of heart disease, while others have no pathological significance. That is to say, some children can hear heart murmurs, but they don't have heart disease. The murmur is caused by the increased blood flow vibration of the pulmonary artery. The murmur produced by this kind of vibration is high and soft, but not very loud. Generally, it is not more than grade II and is not conductive. It is often heard in the apex of the left chest or the second intercostal space of the left edge of the sternum.
This kind of heart murmur is not a symbol of heart disease or congenital heart disease. We call it "functional murmur" or "harmless murmur", which will not affect the growth and development of children. Children's physiological murmurs usually first appear in infancy. The number of children aged 2-3 increases, and the number of children aged 3-7 increases. With the growth of age, organ function gradually matures, heart valve function is complete, physiological murmur will disappear naturally.
However, some noises are loud and rough, and transmit in a certain direction. We call this kind of noise "pathological noise". It is common in children with congenital heart disease because there are abnormal channels or septal defects during embryonic heart development. Because there are abnormal channels between different parts of the heart, that is to say, the normal channels are too narrow. When the blood circulates, the blood flow flows into its narrowed branch river like the surging Yangtze River, producing vortices, There is a noise. Children with congenital heart disease, growth and development will be affected, some a little activity, heart and asthma, some often pneumonia, some anoxic cyanosis. In short, it's different from normal children of the same age.
