Three-dimensional myocardial scar characterization from the endocardium: Usefulness of endocardial unipolar electroanatomic mapping.

abstract：INTRODUCTION:The mechanisms that maintain ventricular fibrillation (VF) are not completely understood. It has been proposed that increased ventricular wall thickness destabilizes VF wavefronts and therefore is an important determinant of VF activation patterns. We hypothesized that if this is the case, then VF patterns...
