Antecubital vein approach for recording his bundle activity in man

Noninvasive recording of electrical activity in the PR segment in man.

“…The method by which His bundle electrograms are obtained is usually that of Scherlag et al (1969) in which an intracavity electrode is introduced via the femoral vein such that two of its poles straddle the tricuspid valve. Alternative approaches using arm veins have also been described (Gallagher et al, 1973;Narula et al, 1973). The limitations and potential dangers implicit in the invasive nature of these techniques have, however, stimulated various workers to explore noninvasive methods of recording His bundle activity.…”
