Unipolar mapping and magnetic resonance imaging of "idiopathic" right ventricular outflow tract ectopy.

Abstract

Radiofrequency catheter ablation of symptomatic ventricular ectopy guided by unipolar mapping was successfully accomplished at the right ventricular outflow tract in a patient who did not exhibit apparent structural heart disease. A "QS" morphology with a fast slope of the downstroke deflection at the successful ablation site was observed on the unipolar electrogram. Focal thinning of the lateral wall of the right ventricular outflow tract was shown in the magnetic resonance image, similar to that reported in patients with "idiopathic" right ventricular outflow tract tachycardia.
