Kawasaki disease: apropos a case with pericardial effusion and persistent extrasystole

: The authors report a case of Kawasaki disease observed in a 3-years and 6-months-old girl, with pericardial effusion and premature cardiac beats. The pericardial effusion disappeared after gamma-globulin i.v. treatment (2 gr/kg); the premature cardiac beats, although progressively reducing, completely disappeared only after 6 months.
