What are the symptoms of Tetralogy of Fallot?

Many babies with Tetralogy of Fallot (TOF) will not have symptoms. In more severe cases, babies will have low oxygen levels in their blood and have a blue color to their skin.

Common symptoms of TOF include:

  • Cyanosis (blue color) of the skin, especially around the lips, fingertips or toes
  • Breathing faster than usual
  • Poor weight gain
  • Heart murmur (an extra sound the heart makes when listening with a stethoscope)
