Outcome Measures

Primary Outcomes (1)

  • Pacing-induced cardiomyopathy

    Time to development of PICM. PICM is defined as ≥ 10% decrease in LVEF resulting in LVEF \< 50% after pacemaker implantation.

    After ≥ 1 years of exposure to right ventricular pacing

Secondary Outcomes (5)

  • Composite endpoint of new-onset heart failure

    After ≥ 1 year of exposure to right ventricular pacing

  • Change in LVEF

    After ≥ 1 year of exposure to right ventricular pacing

  • New-onset atrial fibrillation and/or atrial flutter

    After ≥ 1 years of exposure to right ventricular pacing

  • Change in LV end-diastolic volume

    After ≥ 1 years of exposure to right ventricular pacing

  • Change in LV end-systolic volume

    After ≥ 1 years of exposure to right ventricular pacing

Study Arms (1)

Subjects with a DDD-pacemaker due to high-degree AV block

Device: Right ventricular pacing

Interventions

Right ventricular pacing from a DDD pacemaker implanted due to high-degree AV block

Subjects with a DDD-pacemaker due to high-degree AV block

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Subjects with a normal or near-normal ejection fraction prior to pacemaker implantation who received a DDD-pacemaker due to high-degree AV block ≥ 1 years prior to screening.

You may qualify if:

  • Male or female ≥ 18 years
  • De novo DDD PM implanted at Aalborg University Hospital
  • PM implantation due to advanced AV block
  • Duration of pacemaker treatment ≥ 1 year at time of screening
  • Normal LVEF (≥50%) prior to PM implantation
  • Actively attending follow-up at the PM outpatient clinic at Aalborg University Hospital after PM implantation

You may not qualify if:

  • No written informed consent
  • Baseline TTE not available or insufficient quality for assessment of LVEF
  • Contraindications to a new contrast CT if no previous contrast-enhanced cardiac CT, showing RV lead position, is available
  • RV pacing load \< 40%.
  • Deceased
  • Not attending follow-up at the PM outpatient clinic at Aalborg University Hospital after PM implantation
  • Device complications with removal of original implanted pacing lead \> 3 months after primary implantation
  • Subjects with severe ischemic heart disease and severe valvular heart disease.
  • Terminal illness or unable to provide informed consent at time of screening
