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.
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.
Study Type
OBSERVATIONAL
Enrollment
30
The usual organization of hospitalization of the patients addressed for ventricular tachycardia ablation and his follow-up are not modified by the protocol. .
University Hospital of Toulouse
Toulouse, France
RECRUITINGmeasure assessing change before and after Ventricular Tachycardia Ablation of the non-invasive parameters analysis of the rhythmic risk before and after Ventricular Tachycardia Ablation
non invasive parameters analysis of the rhythmic risk will be evaluated by the evaluation of the T wave alternans
Time frame: 10 minutes and 60 minutes 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
the recurrences of arrhythmias will be evaluated . There will be assessed by the informations reveled by the Implantable automatic defibrillator
Time frame: 3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation
Study of the correlation between the modifications of non-invasive parameters analysis of the rhythmic risk and the success of the ablation procedure
Success of the ablation procedure is defined by the absence of inducible Ventricular Tachycardia at the end of the procedure.
Time frame: 3 months, 6 months and 12 months after the Ventricular Tachycardia Ablation
