Overview
Brief Summary
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.
Detailed Description
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.

Outcomes
Primary Outcomes
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
Secondary Outcomes
- Study of the correlation between the modifications of non-invasive parameters analysis of the rhythmic risk and the success of the ablation procedure(3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation)
- Assessing the correlations of the modifications of the risk criterion after ablation with the recurrences of arrhythmias at one year follow-up(3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation)
