Primary Outcome Measures:
  • Collect ventricular evoked response signal and CRT-D device data during LV only and Bi-Ventricular voltage step-down pacing. [ Time Frame: Minimum of 24 hrs post CRT-D implant. ]
    The primary objective of this study is to collect real-time signals during LV pacing and voltage step-down from patients with implanted COGNIS devices.

Enrollment: 50
Study Start Date: March 2012
Study Completion Date: November 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Pulse Width
One group reflecting two different pulse widths.
Device: Cardiac pacing
Cadiac pacing via a pulse generator and implaned intracardiac leads.
Other Name: COGNIS PG.

Detailed Description:
ELEVATE 3.0 is an acute, prospective, multicenter feasibility study which is randomized within a patient test sequence and pulse width. The study is designed to characterize the performance of LVAT (Left Ventricular Authothreshold) feature.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study population will be a sample of patients with COGNIS CRT-D devices.

Inclusion Criteria:

  • Patients who are age 18 or above, or of legal age to give informed consent specific to state and national law
  • Patients who have a COGNIS CRT-D device implanted for at least 24 hours, with or without an active right atrial lead
  • Patients who have an active LV bipolar or unipolar lead
  • Patients who have an active RV defibrillation lead
  • Patients who are willing and capable of participating in all testing associated with this Clinical Investigation

Exclusion Criteria:

  • Patients who have a COGNIS CRT-D that has less than or equal to one year of battery life remaining
  • Patients who are pacemaker-dependent as defined as VVI 40 without intrinsic atrial or ventricular activity
  • Patients who will not tolerate a pacing pause of up to 6 seconds
  • Patients with a pre-existing unipolar pacemaker
  • Patients who are unable or unwilling to maintain a supine or sitting position for 20-50 minutes
  • Patients enrolled in any concurrent study, without Boston Scientific CRM written approval
  • Women who are pregnant;women of childbearing potential must have a negative pregnancy test within 7 days prior to enrollment.
