Some heart defects cause major problems right after birth.
The main symptom is cyanosis. This is a bluish color of the lips, fingers, and toes that is caused by the low oxygen content in the blood. It may occur while the child is resting or only when the child is active.
Some children have breathing problems (dyspnea). They may get into a squatting position after physical activity to relieve breathlessness.
Others have spells, in which their bodies are suddenly starved of oxygen. During these spells, symptoms may include:
- Breathing too quickly (hyperventilation)
- Sudden increase in bluish color to the skin
Infants may get tired or sweat while feeding and may not gain as much weight as they should.
Fainting (syncope) and chest pain may occur.
Other symptoms depend on the type of cyanotic heart disease, and may include:
- Feeding problems or reduced appetite, leading to poor growth
- Grayish skin
- Puffy eyes or face
- Tiredness all the time
