Brief Summary:

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.

Arm Intervention/treatment
Experimental: Stimulation
All patients included have the stimulation
Procedure: esophagal stimulation
ECG (rest) esophagal stimulation (rest and during effort)

Primary Outcome Measures :
  1. Measurement of effective anterograde refractory period of accessory duct and its evolution for a follow up superior to 10 years [ Time Frame: Day 0 ]

Secondary Outcome Measures :
  1. Triggering a supra-ventricular tachycardia during the stimulation. [ Time Frame: Day 0 ]
  2. Presence of symptoms linked to WPW syndrome during the interval separating the 2 esophageal stimulation. [ Time Frame: Day 0 ]
