His bundle electrogram in congenitally corrected transposition of the great vessels.
His bundle electrogram was recorded in a young adult male with corrected transposition of the great vessels and single ventricle. Prolonged PA and AH intervals, wide diphasic His spike, and normal HV intervals were found. These findings are suggestive of the diffuse nature of conduction delay in this congenital lesion involving intra-atrial, AV nodal, and intra-His regions.
