Ventricular tachycardia in patients with structurally normal hearts

Abstract

Ventricular tachycardia may occur in various clinical settings. But, approximately in 10% of patients with ventricular tachycardia, no definite structural heart disease could be disclosed. Characteristic features of that kind of tachyarrhythmias include absence of obvious structural heart disease, presence of single sustained mo-nomorphic ventricular tachycardia, less well defined underlying electrophysiologic mechanism, and a good arrhythmic prognosis. Ventricular tachycardia in structurally normal hearts mainly originates from right ventri¬cular outflow tract or left ventricle inferoapical septum. The distinction can be made easily with use of surface ECG findings. In this article, characteristic features of idiopathic ventricular tachycardia have been reviewed..
