NCT03611465

Brief Summary

Aim of this study is to collect data from pace mapping performed in three groups of patients : patients presenting ventricular tachycardia and infarction history, patients presenting infarction history without presenting ventricular tachycardia, and in patients without structural heart disease.

Outcome Measures

Primary Outcomes (1)

  • Complete electrophysiology datasets for each group

    Collection of all complete electrophysiology datasets for each group. A data set consists of the electro-anatomical data generated by the Carto system and ECG data collected during topo-stimulation. Collection of all complete electrophysiology datasets for each group. A data set consists of the electro-anatomical data generated by the Carto system and ECG data collected during pace-mapping. It will be considered complete if 100 measurement points have been acquired (pace-mapping and ECG), covering all 17 segments of the left ventricle.

    the electrophysiological exploration is carried out the day after the patient's hospitalization and the datasets are generated just after removing the catheter from the patient, ie about 3 hours later the beginning of the exploration

Study Arms (3)

VT ablation group

OTHER

patients presenting history of myocardial infarction and ventricular tachycardia undergoing a VT ablation

Other: Standard pace-mapping examination

pre implantation group

EXPERIMENTAL

patients presenting history of myocardial infarction but without history of ventricular tachycardia. Patients scheduled for a cardiac defibrillator implantation in primary prevention.

Other: Pace-mapping

control group

EXPERIMENTAL

patients without history of myocardial infarction and without history of ventricular tachycardia, undergoing an ablation in the left atrium for an atrial fibrillation or an accessory pathway ablation.

Other: Pace-mapping

Interventions

Acquire pace-mapping on three distinct populations to better understand the influence of heart disease on electrical conduction.
