Heart Failure Diagnosis

If the doctor thinks your child has symptoms of heart failure, your child may have one or more tests, depending on their condition:

  • A chest X-ray to see if the heart is enlarged
  • An EKG, or electrocardiogram, to check heart rhythm
  • An echocardiogram, or ultrasound of the heart, to look at the heart's structure and the way it is working
  • Exercise testing to check how well their heart and lungs are working
  • A heart catheterization study to get a more detailed look at the heart
