title: Recurrent ventricular tachycardia: an electrophysiologic approach.
abstract: Programmed stimulation of the heart can reproducibly initiate and terminate a sustained tachycardia mimicking clinical disease. This and localization of the site of origin of the tachycardia with endocardial mapping make it possible to directly select the most effective antiarrhythmic agent and to determine whether surgical ablation of the arrhythmogenic locus may be feasible if drug therapy should fail.
