Symptoms of congenital heart disease

summary

In recent years, the prevalence of congenital heart disease in children is getting higher and higher, which has aroused the general concern of the majority of parents. As we all know, children suffering from this disease will have a great impact on their life. So, what are the symptoms of congenital heart disease? Now let's talk about it.

Symptoms of congenital heart disease

  generally speaking, if the blood flows between the parts of the heart too fast or the force is too strong, and causes the heart wall or the great blood vessel wall to vibrate, it will produce noise. In addition, if the normal channel between the various parts of the heart becomes too narrow, or if there is an abnormal channel in the heart, abnormal "vortices" and noises will appear when the blood flows through.

Some children can hear heart murmurs, but there is no heart disease. This kind of murmur is called "functional murmur" or "unrelated murmur", and the cause is not clear. Some people think that it is the blood flow of the pulmonary artery in children that strengthens the normal vibration, so the noise appears. This kind of noise is easy to change, sometimes very light, sometimes obvious, sometimes even disappear. Generally in children with fever, crying, strenuous exercise or lying down after more obvious, and after the fever, quiet or sit up after weakened. So a child's heart murmur is not necessarily a heart disease, let alone a congenital heart disease.

The loudness and pitch of the murmur are also different. Some congenital heart diseases have very small abnormal channels. When the blood flows through, the murmur with higher pitch will appear; However, some abnormal channels have larger caliber, and the murmur produced by blood flow is lower and lighter. Obviously, the larger the abnormal port is, the more serious the lesion is. Therefore, the severity of the disease can not be judged only by the loudness and pitch of the murmur.
