TABLE 1.

Statistics of simulated total activation time 95% (TAT95), QRSd, the ML-score and distance from LV pacing site to the scar area at baseline LBBB activation and BiV pacing at ref-PS and ML-PS in the total patient cohort and groups of responders and non-responders.

Median [25th percentile; 75th percentile]. * - p $<$ 0.05, * - p $<$ 0.01 ML-PS vs. LBBB. $ - p $<$ 0.05, $ - p $<$ 0.01 ML-PS vs. ref-PS. Comparison of dependent groups was performed using Friedman’s test, followed by a pairwise comparison adjusted for multiple comparisons. ^# - p $<$ 0.05, ^# - p $<$ 0.01 Responders vs. Non-responders. Comparison between two independent groups was carried out using Mann-Whitney test.
