Clinical Trial Summary

To compare the efficacy of RV and BiV ATP for the termination of ventricular arrhythmias in patients who are candidates to a cardiac resynchronisation therapy (CRT) and have a Class I or IIA indication for ICD implantation.

The hypothesis of delivering ATP from different sites (RV or BIV) has never been evaluated in a prospective, controlled and randomized study.


Clinical Trial Description

Main objective: Compare efficacy of ATP therapy (Burst, 8 pulses, 88 %, 1 sequence) to terminate all types of ventricular tachycardia (all VTs (FVT+VT)) when delivered in the right ventricle (RV) only versus both ventricles (BiV) resulting in a 10 % difference in favour of BIV ATP

Secondary objectives:

- Compare efficacy of the first BiV and RV ATP (Burst, 8 pulses, 88 %) to terminate fast ventricular tachycardia (FVT)

- Compare efficacy of the first BiV and RV ATP (Burst, 8 pulses, 88 %) to terminate slow ventricular tachycardia (slow VT)

- Compare efficacy of BiV and RV ATP (all ATP therapies) to terminate slow ventricular tachycardia (slow VT)

- Determine the rate of both FVT and VT episodes which are accelerated or degenerates into VF ;


Study Design

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment
