Wolff-Parkinson-White syndrome presenting with steroid-induced bradycardia in a patient with acute rheumatic fever.

Steroids are used in the treatment of acute rheumatic fever with moderate-to-severe carditis. Corticosteroids have several cardiovascular side affects that are more common in adults than in children. Corticosteroid-related bradycardia is a rarely seen side effect. Children with bradycardia following oral corticosteroid use are rarely reported previously. We present a child who developed bradycardia after oral corticosteroid treatment and concurrent Wolff-Parkinson-White pattern.
