 We report a 5-year-old girl who had several Adams-Stokes attacks due to ventricular tachcardia (VT) during a period of 8 months befor admission to our hospital. The first attack of loss of consciousness took place while she was running at the age of 4 years. Electrocardiogram showed ventricular bigeminy and Holter ECG non-sustained VT. In order to prevent Adams-Stokes attack, we first used mexilletine and disopyramide, but in spite of the use of these anti-arrhymic agents, Adams-Stokes attacks did not cease. On electrophysiological study, exercise-induced VT was not evoked but propranolol was effective in reducing VT on exercise. Microscopic myocardial abnormalities similar to those found in cardiomyopathy were observed in right ventricular myocardial biopsy. Adams-Stokes attacks were finally prevented by the use of flecainide.
