Comparison of contraction amplitude between baseline and 6-month follow-up. a EC, MLS and ECR decreased significantly in both patient groups. The responder group had better MLS (p < 0.05) and worse ECR (p < 0.005) than the non-responder group. (Compared to Control Group: *p < 0.05; **p < 0.005; ***p < 0.0005; Compared to baseline Non-responder Group #p < 0.05; ##p < 0.005; ###p < 0.0005.) EC: effective contraction; MLS: maximum longitudinal strain; ECR: effective contraction ratio. b All the parameters of contraction amplitude improved in the responder group and unchanged in the non-responder group. (Comparison between pre-CRT and post-CRT in Responder Group: *p < 0.05; **p < 0.005; ***p < 0.0005) EC: effective contraction; MLS: maximum longitudinal strain; ECR: effective contraction ratio
