|Ventricular Tachycardia||Procedure: ventricular tachycardia ablation|
Sudden cardiac death is a frequent cause of cardiovascular mortality. Numerous rhythmic risk assessment criterion have been described targeting the substratum, the cardiac nervous tone or the trigger of arrhythmias. Development of ventricular tachycardia ablation in the past few years show interesting results preventing the recurrence of ventricular arrhythmias.
Rhythmic risk assessment criterions have never been studied in relation with ventricular tachycardia ablation. The purpose of this study is to explore the modifications of these criterions after ventricular tachycardia ablation.

- Procedure: ventricular tachycardia ablation
The usual organization of hospitalization of the patients addressed for ventricular tachycardia ablation and his follow-up are not modified by the protocol. .
- measure assessing change before and after Ventricular Tachycardia Ablation of the non-invasive parameters analysis of the rhythmic risk before and after Ventricular Tachycardia Ablation [ Time Frame: 10 minutes and 60 minutes after the Ventricular Tachycardia Ablation ]non invasive parameters analysis of the rhythmic risk will be evaluated by the evaluation of the T wave alternans
- Assessing the correlations of the modifications of the risk criterion after ablation with the recurrences of arrhythmias at one year follow-up [ Time Frame: 3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation ]the recurrences of arrhythmias will be evaluated . There will be assessed by the informations reveled by the Implantable automatic defibrillator
- Study of the correlation between the modifications of non-invasive parameters analysis of the rhythmic risk and the success of the ablation procedure [ Time Frame: 3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation ]Success of the ablation procedure is defined by the absence of inducible Ventricular Tachycardia at the end of the procedure.
