What causes a three-year-old to have a heart murmur?

Many parents will find that their three-year-old children have heart murmurs. There are many reasons for this situation. It may be caused by lack of oxygen in the body or congenital heart disease. When facing this situation, people need to pay special attention. Only by understanding the cause can they prescribe the right medicine. The following is a detailed introduction to what causes heart murmurs in three-year-old children.

For children with purple lips and heart murmurs, it is probably caused by lack of oxygen in the body. There are many causes of lack of oxygen in the body, such as heart disease, respiratory disease, and anemia. Avoid the child from getting emotionally agitated, try not to let the child cry, and reduce unnecessary stimulation to avoid increasing the burden on the heart.

It is best to have a heart ultrasound check again, as some murmurs do not necessarily mean there is a problem. Some patients with congenital heart disease may have local blood flow obstruction or vortexes due to sutures, patches, ligation, etc. during surgery, so noise may still exist after the operation. Some patients may also have murmurs due to residual shunt after surgery or valvular stenosis or incomplete closure, so the need for treatment should be determined based on the examination results.

It may be a physiological murmur. The appearance of physiological or functional murmurs does not necessarily mean that the heart is sick, but the result of increased myocardial contractility and faster blood flow. Most of them occur after exercise, when you are emotionally excited or have a fever. Generally, you don't feel anything and don't need treatment, so don't mind it. Suggestions: It is generally believed that heart murmurs are caused by the formation of vortices due to the disordered blood flow in the heart chamber or large blood vessels, which causes the ventricular wall, heart valve or blood vessel wall to vibrate, but it may also be caused by the increased speed of blood flowing through the heart chamber or valve. Heart murmurs can be divided into two categories:

One type is physiological or functional murmur, which often occurs when the heart contracts; the other type is pathological or organic murmur, which can occur when the heart contracts or relaxes. According to the time when the murmur occurs, it is divided into three types: systolic murmur, diastolic murmur and continuous murmur. Murmurs can be divided into 6 levels according to their loudness. Systolic murmurs of level 1/6 are mostly meaningless, level 2/6 may also be physiological, and most of those above level 3/6 are pathological. Diastolic murmurs are mostly diagnostically significant, and even level 1/6 may indicate illness. It must be emphasized that when you know that you have a heart murmur, you should first ask a specialist to make a clear diagnosis. If it is a physiological murmur, it does not necessarily mean that the heart is sick, so don't be too nervous.
