研究概览

简要总结

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.

详细描述

Main objective: Compare & quantify efficacy of two different sequences of burst ATP strategies for the termination of ventricular tachycardia (with Cycle Lenght (CL) of 240ms-320ms) from baseline to 12 months post randomisation in patients who are treated with ATP -8 pulses, 88% versus patients who are treated with ATP -15 pulses, 88%

Secondary objectives:

  • Estimate the efficacy of ATP in successfully treating FVT episodes for patients in primary and secondary prevention
  • Estimate acceleration rate or degeneration of ATP therapy for treating spontaneous FVT episodes in the ATP 15 vs 8 arm
  • Compare the likelihood of syncopal events associated with spontaneous FVT episodes
  • Estimate the percent reduction in number of shocks delivered per patient for treating spontaneous FVT episodes
  • Evaluate different possible predictors of ATP success: VT rate, underlying disease, Anti-Arrhythmic Drugs (AAD), infarct zone, etc.

结局指标

主要结局

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

时间窗: one year

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.

次要结局

  • 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(one year)
