We evaluated 20 patients with idiopathic ventricular tachycardia for structura l abnormalities using magnetic resonance imaging(MRI) and compared them with 20 controls. Two experienced observers interpreted the MRIs. There were no differen ces in incidence of qualitative MRI findings in patients compared with controls. These findings do not favor an association between anatomic abnormalities and a rrhythmia in these patients.
