Central Illustration: Pre-Operative LV Torsional Profile and Post-Operative Survival

(A and B) The legends of upper graphs of LV torsional profile are the same as in Figure 1. (A) LV torsional profiles and Kaplan-Meier curves in the 3 groups. In the lower Kaplan-Meier graphs, the gray line indicates the survivor curve for all 50 patients. (B) LV torsional profiles and Kaplan-Meier curves in the subdivided 2 groups from the WideQRS/CRT group. In the lower Kaplan-Meier graphs, the thin black and red lines are superimposed on the Preserved and Lost group curves in A for comparison (not all statistical analyses are shown, due to a similar trend and a small number).
