Acute myocarditis and ventricular fibrillation as initial presentation of pediatric systemic lupus erythematosus.

ABSTRACT

Acute myocarditis and ventricular arrhythmia are rarely seen as the initial presentation of systemic lupus erythematosus (SLE) in children. We reported the case of a 12-year-old girl with congestive heart failure, acute myocarditis and pericardial effusion as a primary manifestation of SLE. Sudden cardiovascular collapse due to ventricular fibrillation (VF), ventricular tachycardia (VT) and cardiac tamponade occurred. After resuscitation and pericardiocentesis, frequent VF/VT refractory to anti-arrhythmic therapy was supported by venoarterial extracorporeal membrane oxygenation. Early diagnosis and a combination treatment for heart failure, arrhythmias and immunosuppression may result in a favorable outcome.
