Echocardiographic data including septum\u2010to\u2010posterior wall motion delay (SPWMD) and standard deviation of the time to peak systolic velocity (Ts\u2010SD) were collected. Histologic samples from lateral left ventricular (LV) and right ventricular (RV) free wall were analyzed and compared among different groups.

CRT improved cardiac function and corrected intraventricular dyssynchrony with increased LV ejection fraction (LVEF) and decreased SPWMD and Ts\u2010SD (P &lt; 0.05). Histological analysis showed that CRT restored cardiomyocyte diameter (from 4.50 to 6.08 \u03bcm) and collagen volume fraction (from 19.33% to 11.21%) of LV (P &lt; 0.01), but had little effect on RV.
