Inclusion criteria

  • Patient meets current CRT-P indications and be implanted with an SJM CRT-P device with V-V timing and a compatible lead system
  • Patient is able to provide written informed consent for study participation

Exclusion criteria

  • Patient has limited intrinsic atrial activity (≤ 40 bpm)
  • Patient has persistent or permanent AF
  • Patient has a 2o or 3o heart block

Treatment and study plan

QuickOpt

Device

The QuickOpt algorithm will suggest values for programming AV, PV and VV delay.

Primary outcomes

  1. To compare the aortic velocity time integral value derived by the QuickOptTM optimization method with that derived by the standard echocardiography optimization methods

    Time frame: 1 day

Secondary outcomes

  1. Time required for each optimization method considered in this study

    Time frame: 1 day

  2. Effects of any spontaneous cardiac events during the QuickOpt optimization process and these events are not limited to premature ventricular complex (PVC), pacemaker-mediated tachycardia (PMT), atrial fibrillation (AF) and far-field R-wave oversensing

    Time frame: 1 day
