Comparison of opposing wall mechanics during ventricular contraction before and after cardiac resynchronization therapy (CRT). Strain values are measured at mid-systole (50Â %), end-systole (100Â %) and post-systole (125Â %) before (upper panels) and >3Â months after the start of CRT (lower panels). a Septal and lateral longitudinal wall strains; b Anteroseptal and posterior longitudinal wall strains; and c Inferior and anterior longitudinal wall strains. Error bars represent standard errors. CRT, cardiac resynchronization therapy
