Wolff-Parkinson-White Syndrome Anterograde Refractory Period of Accessory Duct (WPW)
The study consists of the realization of a new esophageal stimulation for patients already stimulated 10 years ago.
The investigators would like to make a long term evaluation of the evolution of anterograde effective refractory period of accessory duct in the WPW syndrome.
This study will be realized by esophageal stimulation.

|Official Title:||Long Term Evolution of the Anterograde Refractory Period of Accessory Duct in the Wolff-Parkinson-White Syndrome|
- Measurement of effective anterograde refractory period of accessory duct and its evolution for a follow up superior to 10 years [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
- Triggering a supra-ventricular tachycardia during the stimulation. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
- Presence of symptoms linked to WPW syndrome during the interval separating the 2 esophageal stimulation. [ Time Frame: Day 0 ] [ Designated as safety issue: No ]
