Heart Murmur in Children: Innocent or Worrying?

Most childhood murmurs are harmless. Learn how doctors tell an innocent murmur apart from one that needs attention.

Heart Murmur in Children: Innocent or Worrying?

A heart murmur is simply an extra sound the doctor hears as blood flows through the heart. In children, most murmurs are "innocent" — they come from normal, healthy blood flow and disappear over time.

When is a murmur worth investigating?

  • It is loud, harsh, or heard along with other symptoms
  • The child has breathlessness, poor growth or bluish spells
  • There is a family history of congenital heart disease

An echocardiogram settles the question quickly and painlessly by showing the heart's structure in real time. If it is innocent, no treatment is needed and your child can play freely.
