Wall motion patterns may aid differentiation of LBBB from pacing or infarction; hypothesis-generating for etiology-specific echocardiography.
How do left ventricular wall motions differ between patients with complete LBBB, AV block with RV pacing, anteroseptal infarction, and normal subjects on echocardiography?
The study evaluates left ventricular wall motion abnormalities in complete left bundle-branch block using echocardiography compared to other conditions.
Fujii et al. (1979) studied this question.
