Intra-observer and Inter-observer reproducibility. It shows the inter-observer reproducibility for the value of inter-observer ICC and intra-observer ICC for EC, ECT, ECR, ECTR, MLS, TTO and TTP. It suggested a good reproducibility of all STE parameters. ECT: effective contractile time; EC: effective contraction; ECR: the ratio of effective contraction; ECTR: the ratio of effective contractile time; MLS: maximum longitudinal strain; TTO: time to onset strain; TTP: time to peak strain
