Primary Outcome Measures:
  • Exercise duration [ Time Frame: 12 month post implant ]

Secondary Outcome Measures:
  • Quality of Life (QOL) via Minnesota Living With Heart Failure (MLWH) questionnaire [ Time Frame: 12 month post implant ]
  • NYHA Class Progression [ Time Frame: 12 month post implant ]
  • LVEF [ Time Frame: 12 month post implant ]

Study Start Date: June 2007
Detailed Description:
  • This is a prospective, randomized, double blinded, multicenter study
  • Patients meeting all the enrollment criteria are screened at enrollment and randomized to Group 1 (Pharmacological therapy + Single Chamber ICD) or Group 2 (AVJ Ablation + CRT-D)
  • Screened patients are implanted with a FDA approved SJM ICD/CRT-D with compatible lead system
  • Patients are followed at 1, 3, 6 and 12 months post implant
  • Total # of centers - 20 centers
  • Sample size - 180 patients

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
