Clinical Trial 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.
