Text: Multivariable predictors of reverse remodeling were as follows : (1) either of 2 BV fusion patterns : QRS normalization in leads V1 and V2 (n = 66 [18 %] ; odds ratio [OR] 3. 71 ; 95 % confidence interval [CI] 1. 26-10. 94) or a new or an increased R wave in leads V1-V2 (n = 267 [71 %] ; OR 1. 55 ; 95 % CI 0. 65-3. 65) ; (2) QRS difference -25 ms (OR 2. 35 ; 95 % CI 1. 12-4. 91) ; and (3) good substrate (low to moderate QRS score and LV activation time 110 ms ; OR 2. 94 ; 95 % CI 1. 68-5. 14).
