Objective: Cardiac involvement as pericarditis, myocarditis and valvular disease is common in juvenile idiopathic arthritis (JIA). However, there are few studies concerning systolic and diastolic functions of the left ventricle in children with JIA. P wave dispersion is a sign for the prediction of atrial fibrillation. A recent study found that rheumatoid arthritis patients had an abnormally high P wave duration and P wave dispersion, markers for supraventricular arrhythmogenicity. In this study, we aimed to evaluate P wave dispersion and its relation with diastolic dysfunction of the left ventricle in patients with JIA.
