Shortness of breath
Lightheadedness
Dizziness

Serious heart defects that you're born with (congenital heart defects) usually are noticed soon after birth. Heart defect signs and symptoms in children could include:
Pale gray or blue skin color (cyanosis)
Swelling in the legs, abdomen or areas around the eyes
In an infant, shortness of breath during feedings, leading to poor weight gain
Less serious congenital heart defects are often not diagnosed until later in childhood or during adulthood. Signs and symptoms of congenital heart defects that usually aren't immediately life-threatening include:
Easily getting short of breath during exercise or activity
Easily tiring during exercise or activity
Swelling in the hands
