ABSTRACT
Non-reentrant focal tachycardias occur spontaneously, facilitated by catecholamine infusion, but they cannot be initiated or terminated with programmed stimulation. These tachycardias exhibit early activation before the QRS, however, do not typically show the mid-diastolic potential that is crucial for reentrant tachycardia maintenance. Electrophysiological studies are useful for distinguishing focal from macro-reentrant ventricular tachycardia. We report herein a case of patient without a history of structural heart disease who presented with a focal Purkinje ventricular tachycardia and heart failure. The focal Purkinje ventricular tachycardia was eliminated by radiofrequency catheter ablation. All of the patien's symptoms were improved after ablation.
