Delayed cardiovascular sequelae from Kawasaki syndrome.

The cardiovascular complications of Kawasaki syndrome (KS) are potentially life-threatening. Such complications are usually associated with early stages of the disease and involve symptoms related to myocarditis myocardial ischemia. This report describes an unusual case of a 12-year-old girl with a remote history of KS who presented with supraventricular tachycardia (SVT). The potential relationship between KS and SVT based on results of previous clinicopathologic studies of the conduction system of patients with KS is discussed; this discussion also addresses the importance of early identification, appropriate treatment, and prompt referral once the diagnosis of KS has been made.
