Wolff-Parkinson-White Syndrome Anterograde Refractory Period of Accessory Duct

Nantes University Hospital13 enrolled

Overview

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.
