Functional murmur
Functional murmur
Functional murmur (pronunciation: /ˈfʌŋkʃənəl ˈmɜːrmər/), also known as an innocent murmur, is a type of heart murmur that is not associated with any structural heart disease or abnormality.
Etymology
The term "functional murmur" is derived from the Latin word 'functio' meaning 'performance', and the Latin word 'murmur' meaning 'a low, continuous sound'.
Definition
A functional murmur is a heart sound that is produced when blood flows through the heart in a normal manner. It is typically heard during a routine physical examination and is considered normal in healthy individuals, particularly in children.
Related Terms
- Heart Murmur: An abnormal sound heard during the heartbeat cycle, such as whooshing or swishing, made by turbulent blood in or near the heart.
- Physical Examination: A routine test your doctor performs to check your overall health.
- Heart Sound: The noise that results from the beating heart and the resultant flow of blood through it.
Causes
Functional murmurs are caused by normal blood flow through a healthy heart. Factors that can increase blood flow and therefore increase the likelihood of hearing a functional murmur include anemia, hyperthyroidism, pregnancy, and fever.
Diagnosis
Functional murmurs are typically diagnosed during a physical examination. The doctor will use a stethoscope to listen to the heart sounds. If the murmur is not associated with any other signs or symptoms of heart disease, it is usually considered to be functional.
Treatment
No treatment is necessary for a functional murmur. The doctor will monitor the condition during routine check-ups to ensure that it does not develop into a pathological murmur, which is associated with heart disease.
