NCT00147277

Brief Summary

The purpose of this study is to estimate and quantify the difference in efficacy of two sequences of ATP therapies (burst 15 pulses, 88% versus burst 8 pulses, 88%) during an episode of spontaneous rhythms classified as fast ventricular tachycardia (FVT) via ventricular fibrillation (VF) in patients who have a Class I or II A indication for ICD implantation, and thus to promote the "painless" therapy aspect of ICD treatment and improve quality of life outcomes for patients.

Outcome Measures

Primary Outcomes (1)

  • Efficacy of Anti Tachycardia Pacing (ATP) Therapy to Terminate Fast Ventricular Tachycardia (With Cycle Length of 240ms-320msec)

    Termination of Ventricular Tachycardia is calculated as percentage of successfully terminated episodes, adjusted for multiple events with (GEE) method. This technique yields an average therapy efficacy and 95% CI that is based on number of patients, number of episodes per patient, and magnitude of the correlation between responses within patients.

    one year

Secondary Outcomes (5)

  • Efficacy of ATP in Successfully Treating FVT for Patients in Primary and Secondary Prevention

    one year

  • Acceleration Rate or Degenerated Into VF of ATP for Treating FVT in the 2 Arms

    one year

  • Percent Reduction in Shocks Delivered Per Patient for Treating FVT

    one year

  • Compare Likelihood of Syncopal Events Associated With FVT

    one year

  • Evaluate Different Possible Predictors of ATP Success
