Arrhythmogenic right ventricular dysplasia: an uncommon cause of ventricular tachycardia in young and old?

Right ventricular dysplasia is a little understood condition and is almost certainly underdiagnosed as an important cause of recurrent ventricular tachycardia and sudden death. This report describes two patients with right ventricular dysplasia. Their clinical presentation reflects the remarkable diversity of the disease while the potentially life-threatening nature of their arrhythmias and their lack of response to medical treatment justified the antiarrhythmic surgical procedure of right ventricular disarticulation.
