Brief Summary:
The primary objective is to understand the role of antitachycardia pacing (ATP) in primary prevention patients indicated for 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.

Arm Intervention/treatment
Active Comparator: ATP and Shock
Once tachycardia has been detected and duration met, this group would receive antitachycardia pacing prior to shock therapy.
 Device: Arm 1 (ATP+Shock)
Subjects will be randomized and device programmed to the respective arm.
Experimental: Shock only
Once tachycardia has been detected and duration met, this group would receive shock therapy only.
 Device: Arm 2 (shock only)
Subjects will be randomized and device programmed to the respective arm.

Primary Outcome Measures :
  1. Time-to-First All-Cause Shock [ Time Frame: From 60 days post implant up to five years ]
    Minimum follow up is 18 months and follow up lasts until last patient has completed the 18 month follow up


Secondary Outcome Measures :
  1. • All-cause mortality [ Time Frame: From 60 days post implant up to five years ]
  2. Time to first appropriate shock [ Time Frame: From 60 days post implant up to five years ]
  3. Time to first inappropriate shock [ Time Frame: From 60 days post implant up to five years ]
