Can isolated, symptomatic, frequent ventricular premature depolarizations be a predictor of an inducible ventricular tachycardia? Treatment by radiofrequency catheter ablation.
In this report, we describe a case of sustained ventricular tachycardia of right ventricular outflow tract origin, induced by dobutamine infusion in a patient with symptomatic, frequent ventricular premature depolarizations but no documented clinical ventricular tachycardia. Radiofrequency catheter ablation abolished not only the ventricular tachycardia itself, but also the frequent ventricular premature depolarizations responsible for all the symptomatology. In conclusion, provocation by catecholamine infusion may have a place in the search for an alternative to antiarrhythmic therapy in patients with isolated, frequent and symptomatic ventricular premature depolarizations.
