Abstract
Background Ventricular arrhythmias have been described to originate from intramural locations. Intramural scar can be assessed by delayed enhanced magnetic resonance imaging (DE-MRI ). The objective of this study was to determine whether endocardial voltage mapping by catheter can detect the presence and extent of scar deep within the myocardial wall thickness, using DE-MRI as gold standard.
