Common innocent murmurs in children

  

Children's heart murmurs are quite frequent. A cardiac murmur is nothing more than a sound. Some heart murmurs are really noises produced by heart defects or abnormalities. As blood passes through a ventricular septal defect (a hole in the wall dividing the bottom two chambers of the heart), for example, it creates a particularly distinctive noise. Heart murmurs can also be caused by abnormalities with heart valves, such as aortic valve stenosis. The turbulent flow of blood via the faulty valve might generate a unique sound. Many heart murmurs, on the other hand, are what we refer to as "innocent" heart murmurs. The heart is totally normal with an innocent cardiac murmur. In this scenario, the murmur is just the sound that blood makes as it travels through the heart.
There are a variety of heart murmurs that are completely harmless. Let's take a look at 3 reasonably frequent children's heart murmurs.

Still’s murmur

The Still's murmur, named after English physician George Frederic Still, is by far the most prevalent benign cardiac murmur. It's described as a vibrating noise in several texts. The source of Still's murmur isn't completely understood. According to certain research, children with a Still's murmur are more likely to have an accessory mitral valve chord (sometimes known as a "false tendon") connecting to the ventricular septum. The Still's murmur is by far the most common benign cardiac murmur. It's a little tricky to figure out what the second most frequent benign heart murmur is. It all depends on the age group in question.

Pulmonary flow murmur

A pulmonary flow murmur is just like it sounds. All you hear in a pulmonary flowmurmur is normal blood flow through a normal pulmonary valve. Blood is a liquid that, in some instances, travels rather quickly through the heart. This regular flow can occasionally create additional sounds or noises. One of the most anterior structures in the chest is the pulmonary valve. To put it another way, it's near to the chest wall. As a result, you may be able to hear normal flow over this valve when compared to the other heart valves, which are located, further back in the chest.

At any age, pulmonary flow murmurs might be heard. They are particularly frequent among older children and teens. They're more prevalent in youngsters with thin chest walls, where the heart is physically closer to the stethoscope and therefore easier to hear.

Cervical venous hum

A cervical venous hum is a very frequent form of heart murmur that is completely harmless. The sound of blood flowing properly through the veins above the heart causes it. The jugular veins, in particular, drain blood from the head and neck and link to bigger veins that return blood to the heart. Occasionally, a small angle is created in these connections, resulting in somewhat turbulent blood flow. Usually this is the source of a cervical venous hum. Cervical venous hums are most frequent in youngsters under the age of ten. They're usually only heard while you're sitting or standing up, because gravity pulls blood down into the heart more forcefully in this position. A cervical venous hum in a youngster who is lying flat is quite rare. Light pressure applied to the veins in the neck, or having a kid moves his head to one side, can help to compress the veins and make the murmur disappear.
