Heart murmur
Heartmurmurs are pathological noise perceived on auscultation, murmurs can be differentiated by these characteristics can be constant, crescendo, decrescendo or a mixture of the latter two also in general,sound radiates in the direction blood flow and other features. One of its main causes serious rheumatic fever, whose main characteristic lies in the heart inflammation and degenerative diseases  such asarteriosclerosis. A heart murmur in itself has no specific treatment. The therapy is applied to the heart condition that results in the breath, which can be medication or surgery.
The heart is divided into twoparts, they are separated by a wall which closes, in turn, and each half is divided into two parts, two atria and ventricles. Between the two ventricles and atria are a shut-off valves that regulate theflow of blood from an atrium to a ventricle, which was immediately closed and thus prevents blood is reversed, that is, ventricular reflux into the atrium.
Murmurs are sounds made by blood flowingthrough the heart chambers or valves or through blood vessels near the heart. Heart murmurs can be caused by various factors or diseases, including: faulty heart valves, holes in the walls of the heart,surgical repair of congenital heart defects, fever and anemia.
When a valve is somewhat narrower than usual or does not close properly can give rise to the so-called blow. But also, the breath can bemotivated because they do not fully close the wall that divides the heart into two halves. There always is a blow for a small heart defect can also occur when lies or fever. These circumstances aredifferent and very temporary; pediatricians are called innocent murmurs as it does not reverse damage.
From my point of view a breath is caused by impaired blood flow to the heart compartment to...
