摘要

•LWAT (2D and 3D) can significantly differentiate BiV pacing conditions.•EWI provides 3D visualization of ventricular dyssynchrony change directly after CRT.•EWI can quantify amount of myocardium resynchronized within 24 hours of implantation.•Post-CRT %RMLV is a reliable predictor to distinguish super- from nonresponders.
