What are the murmurs?

Murmurs are sounds that are perceived as the specialist in cardiology auscultation the patient 's heart through a stethoscope. This sound occurs because the blood circulates at high speed, causing turbulence and vibrations which are transmitted to the chest wall and can be heard through the stethoscope.

Causes Blows

Production of puffs can be caused by one or more factors:

• Increased blood flow to pass through a hole (as a normal valve) is the main cause of the innocent murmurs.
• blood flow through a narrow hole (as a narrow valve or estetónica).
• Regurgitation of blood: the blood is not filtered either because of insufficient valve or a congenital defect.
• Vibration free structure within the heart (as a chordal).

It should be noted that blows not have to mean heart disease. In other words, the murmurs are not a disease but a sound, and it is important to keep in mind to avoid false alarms.

innocent heart murmurs

Innocent heart murmurs, also called pathological innocent or not, are those that do not mean any heart disease. These types of murmurs occur especially in children, which is easier to detect with the stethoscope because the distance between it and the heart is shorter and circulation is faster.

Murmurs may be more intense when audible or child heart rate is faster, for example, when excited, exercise, frightened or has a fever.

As the child grows, the innocent murmur becomes more difficult to listen to the point of disappearing in some cases when it has become greater.

In the case of adults, innocent murmurs most often affect pregnant, since there is an overload of blood volume and blood circulates through the valves faster. The anemia associated with pregnancy can also facilitate the emergence of blows, but usually disappear after childbirth. Other possible causes of innocent murmurs in adults can be maintained hyperthyroidism or tachycardias.

What to do if innocent murmurs are detected

First, if the specialist detects murmurs on auscultation, assess medical history and the patient's history to confirm that you are innocent murmurs, ie, that do not mean no problem for the heart.

In some cases, especially in children under two years or a family history of anxiety, the study is completed with an echocardiogram, ie, an ultrasound of the heart that confirms that blows do not reflect any heart disease.

So, if it is confirmed that the heart is healthy (as in most cases), no need to make further revisions, as Blows pose no threat to patient health. In the case of children, they can run, jump and play without any problems and do not need to take medication or care specially.
