May localize variable post-Fallot repair block sites beyond ECG; leaves open prospective validation before clinical use.
Can His bundle electrogram recordings accurately identify the site of complete heart block following surgical correction of tetralogy of Fallot?
His bundle recordings can accurately identify the variable anatomical sites of complete heart block following intracardiac surgery, which may not be predictable from routine ECGs.
Anderson et al. (1972) studied this question.
