Speaker: Fernando Lamounier, Cardiothoracic Surgeon Have you or
a family member been diagnosed with a heart murmur? A heart
murmur is an extra or unusual sound heard during a
heartbeat.Innocent heart murmurs happen in normal hearts and
usually do not cause symptoms. Innocent murmurs are found in
healthy children, pregnant women or can develop because of a
condition. When the condition is treated, the murmur goes
away.Abnormal heart murmurs can cause symptoms such as poor
growth in children, shortness of breath, sweating, chest pain,
dizziness, fainting and fatigue. They can be caused by
congenital heart defects, infections or other conditions that
damage the heart.If you have an abnormal heart murmur, your
doctor will refer you to a specialist who can determine whether
medicine or surgery will improve your heart function.
