In most cases, your doctor will be able to hear your heart murmur by using a stethoscope to listen to your heart (a technique called cardiac auscultation).

Usually the murmur is found during a physical exam for other symptoms, such as chest pain, shortness of breath, fatigue, or the presence of a blue coloring to the skin or fingertips (called cyanosis). Most people with a heart murmur do not have symptoms. Conditions such as pregnancy, anemia, high blood pressure, fever, or an overactive thyroid gland may also cause a heart murmur that comes and goes. In other cases, a heart defect, such as a hole in one of the heart’s walls, can cause a murmur. These valve problems may be present at birth (congenital) or develop later in life because of rheumatic fever, coronary artery disease, infective endocarditis, or aging. Murmurs can occur when blood is forced to flow through a narrowed valve (called stenosis), or when it leaks back through a defective valve (called regurgitation). In these cases, the sound may indicate that blood is flowing through a damaged or overworked heart valve, that there may be a hole in one of the heart’s walls, or that there is a narrowing in one of the heart’s vessels. While some heart murmurs are innocent, others are a sign of a more serious heart problem. In most cases, innocent murmurs disappear when children reach adulthood.

They are common in children and do not require treatment or lifestyle changes.

Some heart murmurs are a harmless type called innocent heart murmurs. But if there is a problem, a murmur may be added to this normal “lub-dub.” By using a stethoscope to listen to your heart, your doctor’s trained ear can tell if the abnormal sound indicates turbulence. The second “lub-dub” is the sound of the aortic and pulmonary valves closing soon after. The sounds are often described as a constant “lub-dub, lub-dub.” The first “lub-dub” is the sound of the mitral and tricuspid valves closing.
