Multi-source atrial tachycardia in children

Chaotic atrial tachycardia (CAT) in children, also known as multi-source atrial tachycardia or dysrhythmic atrial rhythm, mostly occurs in infancy, usually with a normal heart structure and a persistent attack. The law is difficult, but it can be relieved by itself and the prognosis is good. Adult cases occur in the elderly, often accompanied by chronic obstructive pulmonary disease, severe illness, and poor prognosis. The two are clearly different.
