Reporting Groups
  Description
ICD Implant Without Defibrillation Testing Patients in this arm were implanted with their ICD without having the defibrillation test performed at implant. No VF induction was performed.
ICD Implant With Defibrillation Testing Patients in this arm were implanted with their ICD and VF induction was performed followed by shock delivery to test shock efficacy at implant.
