Functional murmur

Functional murmur is a type of heart murmur that is primarily caused by blood flow through the heart and blood vessels. Unlike pathological murmurs, functional murmurs are not associated with any underlying heart disease or condition. They are also referred to as innocent, physiological, or benign murmurs.

Causes

Functional murmurs are typically caused by increased blood flow through the heart. This can occur due to a variety of reasons, including exercise, pregnancy, fever, and anemia. In children, functional murmurs are often due to the normal growth and development of the heart.

Symptoms

Functional murmurs are usually asymptomatic, meaning they do not cause any symptoms. They are often discovered during a routine physical examination when a doctor listens to the heart with a stethoscope.

Diagnosis

The diagnosis of a functional murmur is typically made based on a person's medical history and a physical examination. Additional tests, such as an echocardiogram, may be performed to confirm the diagnosis and rule out any underlying heart conditions.

Treatment

Since functional murmurs are not caused by any heart disease or condition, they do not require any specific treatment. However, it is important for individuals with a functional murmur to have regular check-ups to monitor their heart health.
