Impact of Interelectrode Spacing on Ventricular Tachycardia Substrate Mapping: Insights Into 3-Dimensional Characteristics of the Arrhythmogenic Substrate.
BACKGROUND Re-entrant ventricular tachycardia (VT) circuits often involve 3-dimensional activation across the endocardium, epicardium, and mid-myocardium, highlighting the importance of comprehensive substrate assessment. Wider interelectrode spacing may incorporate broader-field electrical components that are less app...
