Heart Murmur: Signs and Symptoms


What are the signs and symptoms of heart murmurs?

Usually, murmurs have no visible signs or symptoms. The most common way murmurs are diagnosed is during a routine pediatric checkup when your child’s doctor listens to the heart. Innocent murmurs will have no other symptoms.

Murmurs are classified by how loud they are. Louder murmurs are usually more serious than quieter ones.

If your child has an abnormal heart murmur, there may be symptoms that indicate there is an underlying heart condition. These symptoms may include:

  • Shortness of breath
  • Trouble feeding and gaining weight
  • Sweating while feeding
  • Fatigue
  • Cyanosis (a blue tint to the lips and skin)

Please tell your doctor if you notice these symptoms in your child.
