A 1-year and 9-month-old boy presented with fever, red eyes, redness of his lips, rash on his trunk and erythema around a BCG scar. On the 8th day of illness, he was diagnosed with incomplete Kawasaki disease and received intravenous immunoglobulin at a dose of 2 g per kilogram. The fever subsided the next day, but his ECG showed second-degree atrioventricular (AV) block (Wenckebach type). Because he was not able to sit up and was not active, he was transferred to our hospital on the 11th day of illness. He was followed up with oral aspirin therapy and his diagnostic symptoms of Kawasaki disease were relieved without any coronary artery abnormality. Second-degree AV block disappeared on the 13th day of illness and first-degree AV block disappeared on the 16th day of illness. He was able to sit up on the 16th day of illness and to walk around on the 18th day, and was discharged on the 19th day.
Several types of arrhythmia have been reported as one of the complications of Kawasaki disease. We studied the frequency of arrhythmias in Kawasaki disease patients in our hospital. During fifteen years, 5 out of 100 Kawasaki disease patients had arrhythmias. This result is lower than in previous reports. Although the prognosis of arrhythmias associated with Kawasaki disease is generally good, it is necessary to be careful of the development of arrhythmias.
