According to the Mayo Clinic, an innocent murmur typically doesn't have any symptoms or require any type of treatment, and it's usually caused by blood flowing too quickly through the heart. Depending on the cause of an innocent murmur, it may eventually go away or last a lifetime. A patient may not notice any symptoms when diagnosed with an abnormal murmur either. The chances of developing a heart murmur increase if there is a family history of heart defects, high blood pressure, or the patient experienced a heart attack in the past.

A few signs a person may have a heart condition include shortness of breath, chest pain and dizziness.
