Implication

His bundle electrography may delineate conduction lesions in heart block; leaves open its impact on management and outcomes.

Structured PICO

P
Population
3 patients with heart block who subsequently died
I
Intervention
His bundle electrogram recording and postmortem serial sections of the conduction system
O
Outcome
Correlation between electrophysiological site of block and postmortem anatomical lesionssurrogate

His bundle electrogram recordings accurately reflect the anatomical site and extent of conduction system lesions in patients with heart block.
