Noninvasive mapping of ventricular arrhythmias

Card Electrophysiol Clin. 2015 Mar;7(1):99-107. doi: 10.1016/j.ccep.2014.11.014. Epub 2014 Dec 24.

Abstract

Several decades of research has led to the development of a 252-lead electrocardiogram-based three-dimensional imaging modality to refine noninvasive diagnosis and improve the management of heart rhythm disorders. This article reviews the clinical potential of this noninvasive mapping technique in identifying the sources of electrical disorders and guiding the catheter ablation of ventricular arrhythmias (premature ventricular beats and ventricular tachycardia). The article also briefly refers to the noninvasive electrical imaging of the arrhythmogenic ventricular substrate based on the electrophysiologic characteristics of postinfarction ventricular myocardium.

Keywords: Arrhythmogenic substrate; Electrical scar; Noninvasive mapping; Ventricual premature beat; Ventricular arrhythmias; Ventricular tachycardia.
