Maps of ventricular WT.

<p>(A–B) Anterior and posterior views. (C–D) Cutaway views of right and left sides of ventricular septum. (E–F) Cutaway views of posterior and anterior endocardium. All 10 endocardial PVC initiation locations are shown. Rectangle color indicates whether ectopic stimuli originating from that site induced sustained arrhythmia. Asterisk (in E) indicates a region of WT expansion in the RV free wall (see text for further detail). WT: wall thickness.
