Child heart murmur is a heart attack it?

The normal development of children into kindergarten when a medical examination found that heart murmur. Heart murmur means outside the normal heart sounds the voice of a longer duration. Pediatric heart murmur is not necessarily sick! Pediatric heart murmur, there are two circumstances, first, physiological noise, and the other is pathological murmur.

Physiological noise

Pediatric chest wall thin, fast heartbeat, fever, tension and after exercise, check the heart with a stethoscope, the comparison can sometimes hear the gentle sound like the same briefing, these noises are often physical in nature, no impact on human health. According to statistics, more than half of healthy children can be rational Yousheng noise.

Physiological noise has the following characteristics: noise parts than its predecessor, both systolic murmur (heart contraction produced), short duration, to reduce the sound, with the posture, breathing and movement and change, such as in sports, crying, or when the Enhanced Position , when sitting quietly or weakened. Physiological noise was particularly prevalent in the more than 2 ~ 3-year-old child, a maximum of 3 to 7 years old, with age, organ function of mature, fully functioning heart valve, physiological murmur will disappear naturally.

A small number of noise caused by the disease, such as fever, anemia or hyperthyroidism in children, because lack of oxygen, to reduce blood viscosity and other reasons, the blood flow to accelerate, although there was no unusual heart itself would have a heart murmur, the murmur known as functional noise. When the original cure disease, the noise will also disappear.

Pathological murmur

Congenital heart disease was particularly prevalent in children, noise lasted for a long time, and the ring tone and rough, such as atrial septal defect, ventricular septal defect, patent ductus arteriosus, tetralogy of disorders, heart disease itself and the opening and closing valve abnormalities , blood flows generated in the vortex turbulence caused by abnormal noises.

Congenital heart disease is a common disease in children, a higher rate of incidence. Reported in the literature abroad, and its incidence of live births accounted for about 0.4% ~ 0.8%. China's annual births, about 10 million suffer from congenital heart disease.

Such children are often accompanied by shortness of breath, recurrent respiratory tract infection or pneumonia, sweating, and heart beat faster, edema and other symptoms, physical strength than the same age children, growth retardation, and some children have lips bruising, mild activity, walking would like to squat rest, or the relevant section of symptoms such as pain. Some children usually have no symptoms, growth and development of normal activity levels also great, as with normal children, only in the occasional cold, respiratory infections when they seek medical treatment, doctors found physical heart murmur was found suffering from congenital heart disease.

At present, children with congenital heart disease diagnosis and treatment of technology has reached the international level, common heart malformations in the surgical success rate of more than 95%, survival of children after long-term result is good, the majority have normal quality of life.
