Is left bundle branch block pattern on the ECG caused by variable ventricular activation sequence?

ConclusionsBoth typical LBBB and LBBB ‐like pattern might be associated with constant activation sequence regardless of etiology and scar localization. Activation initiation in RV apex, not LV activation sequence can be surrogate for left axis deviation. CRT caused inter‐ and intraventricular LV resynchronization without significant ly changed RV activation sequence and duration.This article is protected by copyright. All rights reserved
