  Purpose

The main objective is to research for genetic factors involved in the extreme modifications of the QT interval of the electrocardiogram in answer to a pharmacological stimulation (sotalol) and physiological stimulation in the apparently normal general population.

The phenotypic characterization, based on the ventricular repolarisation dynamics will be used aiming at term of the predictive genetic factors of the acquired long QT syndrome

Primary Outcome Measures:
  • The elongation of the corrected interval QT duration 3 hours after the unique oral taking of an 80 mg dose of Sotalol. [ Time Frame: 3 hours after the taking of Sotalol ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Constitute a biological base and a phenotypic base of resources which will allow to define answer phenotypes to the implemented dynamic tests [ Time Frame: At the inclusion visit ] [ Designated as safety issue: No ]
  • Look for associations between these phenotypes of electrocardiographically answer and mutations or polymorphisms. [ Time Frame: At the inclusion visit ] [ Designated as safety issue: No ]
