Association of Sinus Node Dysfunction, Atrioventricular Node Conduction Abnormality and Ventricular Arrhythmia in Patients With Kawasaki Disease and Coronary Involvement

Abstract

Although there was no relationship between coronary stenosis or obstruction and the EPS parameters, the incidence of abnormal sinus node and atrioventricular node function is apparently higher in KD patients than in the normal population. These functional abnormalities may possibly be caused by myocarditis or an abnormal microcirculation in the sinus node and atrioventricular node artery. In some patients, myocardial ischemia may provoke malignant ventricular arrhythmia.
