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

Long Term Evolution of the Anterograde Refractory Period of Accessory Duct in the Wolff-Parkinson-White Syndrome

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.

• Informed consent signed
• Diagnosis of Wolff-Parkinson-White syndrome
• No procedure of ablation of accessory duct
