Is all heart disease in children congenital?
No, but most is. These defects are usually but not always diagnosed early in life. Rarely, heart disease is not congenital but may occur during childhood such as heart damage due to infection. This type of heart disease is called acquired; examples include Kawasaki disease and rheumatic fever. Children also can be born with or develop heart rate problems such as slow, fast, or irregular heart beats, known as “arrhythmias”.
