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 ...
