Summary

This study aims at comparing the recurrence rates of ventricular tachycardia ablated after being mapped by 2 different techniques.

Detailed description

The study participants are patients presented with recurrent ventricular tachycardia. They will be divided into 2 groups in terms of mapping. The first group will use mapping during sinus rhythm to identify late potentials that may be incriminated in the tachycardia circuit. The other group will undergo mapping during right ventricular extrastimulus pacing to unmask hidden potentials. The identified potentials will be ablated in both groups.

Conditions

• Tachycardia, Ventricular

Interventions

Type	Name	Description
PROCEDURE	Radiofrequency ablation	Both groups will undergo radiofrequency ablation of potentials likely responsible for the tachycardia. Those potentials are identified by the formentioned 2 distinct methods.
