Diagnosis

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.
