My doctor told me I have a heart murmur. What is a heart murmur and what are the symptoms?

A heart murmur is an abnormal sound that can be heard with a stethoscope when blood flows through the heart. It’s usually caused by a problem in the heart valves, such as a leaky valve or a narrowing of the valve. The most common symptom of a heart murmur is a “whooshing” noise that can be heard when listening to your heartbeat. Other symptoms may include shortness of breath, fatigue, chest pain, dizziness, and fainting. If you have any of these symptoms, it's important to see your doctor for further evaluation.
