Diagnosis Heart & Vascular

Tetralogy of Fallot

A complete cardiac evaluation for tetralogy of Fallot will include:

  • Echocardiography, in which a picture is made of the heart by using sound waves
  • Chest X-ray
  • Electrocardiogram (EKG or ECG), which records the heart's electrical activity
  • Examination of the oxygen content of arterial blood. This is usually done with an oximeter, a little light that can be placed on a finger. Sometimes, a blood sample may be drawn from an artery in the wrist and checked for content of oxygen, carbon dioxide and acidity.
