Secondary Outcome Measures:
  • to track all programming changes made to the LV pacing/sensing configurations [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Enrollment: 260
Study Start Date: November 2004
Study Completion Date: December 2008

Intervention Details:
    Device: CRT device
    market approved CRT device
Detailed Description:
Cardiac resynchronization therapy (CRT) is an accepted treatment for selected heart failure patients. This therapy is delivered using a device (pacemaker (PM) +/- defibrillator (ICD) ) and leads placed in the right atrium (RA), right ventricle (RV) and left ventricle (LV). Rates of LV lead implantation failure and post operative lead related have decreased dramatically over the years, however, the incidence of lead dislodgement and phrenic nerve stimulation is still high. This study is a prospective evaluation of the benefits of having various pace/sense electrode configurations available in a CRT system.
