When to Seek Medical Care

Sometimes tetralogy of Fallot goes undiagnosed for several months to a year. Diagnosing conditions such as tetralogy of Fallot is one of the goals of routine checkups with your doctor. Take your child to his or her health care provider if the child develops a bluish color, has breathing difficulties, seizures, fainting, fatigue, slow growth, or developmental delay. A medical professional should establish the cause of these problems.

If you cannot reach your child's health care provider or if the child develops any of the following symptoms, take the child to a hospital emergency department right away:

• Bluish discoloration
  
  
• Trouble breathing
  
  
• Seizures
  
  
• Fainting
  
  
• Extreme fatigue or weakness
