May identify occult contralateral delay missed by surface ECG in bundle-branch block; leaves open whether routine His recording refines risk stratification.
Does His bundle electrogram recording improve the localization of conduction defects in patients with bundle-branch block?
His bundle electrograms provide critical diagnostic information for localizing conduction disturbances in patients with bundle-branch block, particularly in identifying contralateral bundle disease.
Ranganathan et al. (1972) studied this question.
