Dr., professor of cardiology at Virginia Commonwealth University School of Medicine. In some cases, a heart murmur can be a sign of heart valve malfunction, Kenneth Ellenbogen said. In this respect reports Live Science.
A heart murmur is an acoustic phenomenon associated with changes in blood flow in the heart and blood vessels. You can be noticed by your doctor by listening to your heart rhythm with a stethoscope. Sometimes extraneous sounds are an individual feature of the body and do not pose a danger. However, in some cases, murmurs may indicate a heart valve malfunction.
The doctor explained that the heartbeat sound was caused by the valves closing when the heart muscle contracts. Blood is pumped from the left and right atrium to the ventricles, which send it to the arteries. The valves between each pair of atria and ventricles close, preventing the backflow of blood.
A murmur may occur when the valves do not close tightly enough and some of the blood returns to the ventricles. In addition, uncharacteristic sounds can be symptoms of heart defects, infections of the mucous membranes and rheumatism.
Heart murmurs that are not caused by structural abnormalities or heart disease are called physiological murmurs. They are seen in children and adolescents. In a body experiencing a growth spurt, blood must flow faster to keep up with the spread. This process may be accompanied by sounds other than heartbeat.
It is stated that you should consult a doctor and undergo the necessary examinations to determine the cause of your heart murmur.
