Arrhythmogenic right ventricular dysplasia.
A 23-year-old man presented with recurrent exercise-induced ventricular tachycardia (VT), complicated by systemic embolisation. Catecholamine--sensitive VT was reproduced on exercise testing and programmed electrical stimulation, displaying features suggestive of enhanced automaticity as well as re-entry. Both 2D-echocardiography and gated heart pool scan showed localised dyskinetic bulging in the right ventricle. A diagnosis of arrhythmogenic right ventricular dysplasia was made. This condition should be excluded in all young patients with otherwise unexplained ventricular arrhythmias.
