Abstract
A 42-year-old man was hospitalized for investigation of repeated episodes of ventricular fibrillation (Vf). Electrocardiogram (ECG) showed typical features of Brugada syndrome. Echocardiography, coronary angiography and endomyocardial biopsy specimen were normal. 123I-MIBG scintigraphy showed homogeneous reduction of uptake. The patient demonstrated 17 episodes of Vf in 1 day, but these were terminated by direct cardioversion. Spectral analysis of heart rate variability demonstrated increased sympathetic activity followed by Vf attacks.
