Key result
Atrial pacing at multiple sites successfully predicted the site of anomalous pathways in all 5 patients, with the shortest stimulus-delta interval (60-80 ms) indicating the insertion site.
Why the study?

Multi-site atrial pacing may help localize accessory pathways in WPW; leaves open its reliability and clinical adoption beyond small series.

Does atrial pacing at multiple sites predict the site of pre-excitation in patients with Wolff-Parkinson-White syndrome?
Atrial pacing at multiple sites accurately predicts the location of anomalous pathways in WPW syndrome, aiding in the differentiation of right posterior, left posterior, and septal pre-excitation.
Denes et al. (1977) conducted an observational in Wolff-Parkinson-White syndrome (n=5). Atrial pacing at multiple sites was evaluated on Prediction of the site of pre-excitation. Atrial pacing at multiple sites successfully predicted the site of anomalous pathways in all 5 patients, with the shortest stimulus-delta interval (60-80 ms) indicating the insertion site.
