What are heart murmurs?
A heart murmur is an abnormal or extra sound from a heartbeat. While the majority of cases are harmless, some signal underlying problems that require medical attention.
Types of heart murmurs
There are two types of heart murmur:
Innocent heart murmurs
These are harmless and make up the majority of cases. They are often caused by rapid blood flow within or near your heart.
Abnormal heart murmurs
These are caused by a heart condition, often a congenital defect (a structural problem present at birth) in children or heart valve disease in adults.
Heart murmur: what you should know
- Heart murmurs are common in children and often part of normal development — roughly 30 percent of children will have a murmur at some point. Less than 1 percent of children will actually have something wrong with their heart.
- The only symptom experienced by someone with an innocent heart murmur is the murmur itself. But abnormal heart murmurs are accompanied by symptoms of the underlying heart problem and may include the following:

A thorough examination by your physician is usually enough to root out the worrisome murmurs from the harmless ones. Further testing may include an ultrasound of the heart (echocardiogram).

The approach of physicians at Rush depends on the type and severity of the condition.
