1. Venn diagram of patients with paired pre-cardiac resynchronisation therapy (CRT) and post-CRT echocardiograms.
Venn diagram of patients with paired pre-cardiac resynchronisation therapy (CRT) and post-CRT echocardiograms. Red circle: patients with radial dyssynchrony (Dyss). Blue circle: patients with left bundle-branch block (LBBB). Green circle: patients with QRS ≥150 ms. The area within each geometric shape is proportional to the number of patients within each group. Shaded areas represent patients with two of the three variables present.
