Still's murmur

Still's murmur (also known as innocent murmur or functional murmur) is a type of heart murmur commonly found in children. It is named after George Frederic Still, a British pediatrician who first described it.

Description

Still's murmur is a benign, vibratory, early to mid systolic murmur that is most commonly heard in healthy children aged 3 to 7 years. It is often described as a musical, vibratory, or twanging sound. The murmur is usually best heard at the left lower sternal border and apex, and it may increase in intensity with fever or exercise.

Diagnosis

The diagnosis of Still's murmur is typically made by a cardiologist or pediatrician based on the characteristic sound of the murmur on auscultation. Additional tests such as an electrocardiogram (ECG) or echocardiogram may be performed to rule out structural heart disease, but these tests are usually normal in children with Still's murmur.

Prognosis

Still's murmur is considered a normal variant and does not indicate heart disease or predict future heart problems. The murmur usually disappears by adolescence, but it may persist into adulthood in some individuals.
