Multivariable predictors of reverse remodeling were as follows : ( @ ) either of @ BV fusion patterns : QRS normalization in leads V@ and V@ ( n = @ -LSB- @ % -RSB- ; odds ratio -LSB- OR -RSB- @ ; @ % confidence interval -LSB- CI -RSB- @-@ @ ) or a new or an increased R wave in leads V@-V@ ( n = @ -LSB- @ % -RSB- ; OR @ ; @ % CI @-@ @ ) ; ( @ ) QRS difference -@ ms ( OR @ ; @ % CI @-@ @ ) ; and ( @ ) good substrate ( low to moderate QRS score and LV activation time @ ms ; OR @ ; @ % CI @-@ @ ) .
