Clinical Trial 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.
