Innocent Murmurs

What is an Innocent Murmur?

An innocent murmur is a harmless sound made by blood flowing through the heart. It is common in children and does not indicate heart disease or a structural problem.

Key Facts

  • Found in up to 67% of children

  • Usually detected during routine checkups

  • Does not require treatment or lifestyle changes


  • Often disappears as the child grows

Will my child outgrow it?

Yes! Most innocent murmurs disappear by adolescence as the chest wall thickens and blood flow patterns change.

Does My Child Need to Avoid Any Activities?

No restrictions! Children with innocent murmurs can:

  • 
Play sports


  • Run and be active


  • Live a normal, healthy life

When to Seek Medical Attention

While most murmurs are innocent, some may indicate an underlying condition. See a doctor if the murmur is accompanied by:

  • Rapid breathing or difficulty feeding (in infants)

  • Blue skin (cyanosis)

  • Poor weight gain

  • Fainting or dizziness

If your child has an innocent murmur, there’s no need to worry! It’s a normal finding, and your child can grow up healthy and active. Always consult your doctor if you have concerns.
