Tetralogy of Fallot: Signs and Symptoms

What are the signs and symptoms of tetralogy of fallot?

Children with this heart condition often have a blue tint to their skin, lips and fingernails. This is called cyanosis and means that not enough oxygen-rich blood is reaching the child’s body.

Sometimes, a baby only shows signs of cyanosis after crying or feeding. These episodes are called “Tet spells.”

Other symptoms of tetralogy of Fallot are:

  • Trouble feeding
  • Poor growth and weight gain
  • Fainting
  • Clubbed fingers

If your child is having any of these symptoms, especially cyanosis, contact your doctor immediately.
