Assessment of Primary Prevention Patients Receiving An ICD - Systematic Evaluation of ATP

Not Applicable
Completed
Conditions
Sudden Cardiac Death
Interventions
Device: Arm 1 (ATP+Shock)
Device: Arm 2 (shock only)
Registration Number
NCT02923726
Lead Sponsor
Boston Scientific Corporation
Brief Summary

The primary objective is to understand the role of antitachycardia pacing (ATP) in primary prevention patients indicated for implantable cardioverter-defibrillator (ICD) therapy and programmed according to current guidance of higher rate cut-offs and therapy delays. The time to first all-cause shock will be tested in subjects with standard therapy (ATP and shocks) compared to subjects programmed to shock only to assess equivalency.

GroupInterventionDescription
ATP and ShockArm 1 (ATP+Shock)Once tachycardia has been detected and duration met, this group would receive antitachycardia pacing prior to shock therapy.

Primary Outcome Measures
NameTimeMethod
All-Cause Shock5 years

The incidence of all-cause shocks in subjects programmed with shocks only will be compared with subjects programmed to standard therapy (ATP and shock) to assess equivalency. All shocks delivered by the device were adjudicated by an external committee as to whether they were appropriately or inappropriately delivered. All shocks, appropriate and inappropriate, contributed to the evaluation of this endpoint.

Secondary Outcome Measures

All-Cause Shock or Death From Any Cause5 years

Appropriate Shock5 years

Inappropriate Shock5 years

incidence of first inappropriate shock All shocks delivered by the device were adjudicated by an external committee as to whether they were appropriately or inappropriately delivered. Inappropriate shocks contributed to the evaluation of this endpoint.
