Key result

His bundle electrogram recording and pacing were evaluated in 20 patients with typical Wolff-Parkinson-White syndrome to examine the functional properties of the accessory conduction pathway.

Why the study?

Does His bundle pacing clarify the functional properties of the accessory conduction pathway in patients with Wolff-Parkinson-White syndrome?

Population

Implication

His bundle pacing may delineate accessory pathway properties in WPW; leaves open its diagnostic role in contemporary ablation.

Key Points

The study aims to evaluate the functional properties of accessory conduction pathways in Wolff-Parkinson-White syndrome through His bundle pacing.
Analyzed 20 patients with typical WPW patterns (shortened PQ interval, delta wave, widened QRS complex) — 10 type A and 10 type B.
Used His bundle electrogram recording techniques introduced by Scherlag and co-workers.
Bipolar electrode catheters were positioned via right femoral vein for pacing and recording atrial activity.
Findings from His bundle pacing provide new insights into the functional properties of accessory conduction pathways in WPW syndrome.
Successful pacing results in type-specific responses, indicating the need for tailored interventions.

Does His bundle pacing clarify the functional properties of the accessory conduction pathway in patients with Wolff-Parkinson-White syndrome?

Population

20 patients with typical Wolff-Parkinson-White (WPW) syndrome (10 type A, 10 type B) undergoing His bundle electrogram recording and pacing.

Exposure

His bundle electrogram recording, atrial pacing, and His bundle pacing using bipolar electrode catheters introduced via the right femoral vein.

Outcome

Functional properties of the accessory conduction pathway (electrophysiologic findings obtained by His bundle pacing).surrogate

This early electrophysiologic study describes the technique and utility of His bundle pacing to evaluate the accessory conduction pathway in patients with Wolff-Parkinson-White syndrome.
