Figure 2 Left ventricular ejection fraction (LVEF) at baseline and after six months in patients with a septal-to-posterior wall motion delay (SPWMD) of 130 ms (open circles) and <130 ms (closed circles). Date expressed as mean values ± SEM. *p < 0.05 vs. baseline; p < 0.05 vs. patients with an SPWMD of <130 ms.
