Outcome Measures

Primary Outcomes (1)

  • Acute change in QRS duration due to CRT with NAVH, relative to intrinsic conduction

    Acute changes in surface ECG QRS duration resulting from Cardiac Resynchronization Therapy (CRT) with Negative Atrioventricular Hysteresis (NAVH) over a range of programmable values

    1 day

Secondary Outcomes (2)

  • Acute changes in LV pressure-volume hemodynamics due to CRT with NAVH, relative to intrinsic conduction

    1 day

  • Change in QRS duration after one day of CRT with NAVH, relative to intrinsic conduction

    1 day

Study Arms (1)

CRT+NAVH

Surface ECG and pressure-volume loop recordings will be taken during the adjustment of programmable Cardiac Resynchronization Therapy and Negative Atrioventricular Hysteresis settings at the device implant procedure

Device: CRT+NAVH

Study Population

Enrollment will include patients scheduled to be implanted with MultiPoint Pacing-enabled SJM Quadripolar Pacing Systems

You may qualify if:

  • Scheduled for implantation of an MPP-enabled SJM Quadripolar CRT Pacing System
  • QRS duration \> 140 ms
  • Left bundle branch block documented
  • Ability to provide informed consent for study participation
  • Willing to comply with the study evaluation requirements
  • At least 18 years of age

You may not qualify if:

  • Resting ventricular rate \>100 bpm
  • Intrinsic PR interval \> 300 ms
  • Paroxysmal or persistent atrial tachycardia or atrial fibrillation documented
  • A recent myocardial infarction, ablation, drug intoxication, electrolyte imbalance, or any condition within the last 90 days that would be contraindicated for CRT programming changes in the opinion of the investigator
  • Women who are pregnant or who plan to become pregnant during the study
