Illustration of the Novel Pacing Approaches in CRT (Left) Illustration of the 4 novel pacing approaches in CRT: 1. His bundle pacing, 2. LV endocardial pacing, 3. LV septal pacing, 4. Wireless pacing in the LV endocardium. The fast conduction layer along the right ventricular and LV endocardium is depicted in orange and the Purkinje system is depicted in yellow. (Right) (A) Proposed mechanism of the benefit of His bundle pacing in the left bundle branch block (LBBB). The His bundle the fibers for the right bundle branch(RBB) and LBB are longitudinally dissociated so that in case of (B) proximal block, pacing in the His bundle can capture fibers in the LBB. (C) This option is likely not beneficial in case of distal block. AVN = atrioventricular node; HB = His bundle; LAF = left anterior fascicle; LPF = left posterior fascicle; other abbreviation as in Figure 1.
