Atrial Septal Defect Symptoms and Diagnosis
Symptoms of Atrial Septal Defect
A small atrial septal defect (ASD) may cause no symptoms at all or none until later in childhood or adulthood.
A larger defect may cause symptoms soon after birth. Children may have symptoms such as tiring easily when playing, breathing fast, having to work hard to breathe (shortness of breath), or having abnormal heartbeats.
