Three cases of exercise-induced ventricular tachycardia with associated right ventricular dysplasia are described. In each case, patients experienced ventricular tachycardia during treadmill tests. In all three patients, echocardiography or nuclear scintigraphy revealed a dilated right ventricle with reduced ejection fraction; cardiac catheterization with angiography also showed a dilated and hypokinetic right ventricle in each case. Two patients underwent electrophysiology studies that showed an inducible ventricular tachycardia originating from the right ventricular outflow tract. All three patients were treated with single agent antiarrhythmic drugs that controlled their ventricular tachycardia.
