High mean entropy calculated from cardiac MRI texture analysis is associated with anti ‐tachycardia pacing failure

ConclusionsOur findings suggest lower scar heterogeneity (mean entropy) is associated with successful ATP whereas higher scar heterogeneity is associated with more aggressive VAs unresponsive to ATP requiring shock therapy which may be due to inability of the paced wavefront to propagate through scar and terminate the VA circuit.This article is protected by copyright.
