In this month's Case Study, Kataoka and colleagues report a patient who experienced three episodes of syncope over the course of 2 years. Electrocardiography and 24h Holter monitoring revealed occasional premature ventricular complexes arising from the right ventricular outflow tract which, on a subsequent occasion, triggered an arrhythmic episode that degenerated into ventricular fibrillation. She was treated with radiofrequency catheter ablation and was fitted with an implantable cardioverter-defibrillator.
