Brief Summary

The implantation of a pacemaker and conventional cardiac pacing from the right ventricle (apex or septum) is an effective and safe therapy for the treatment of patients with atrioventricular block and bradycardia.

Pacemaker-induced cardiomyopathy

Outcome Measures

Primary Outcomes (1)

  • Compare the incidence of pacemaker-induced heart disease

    Pacemaker induced cardiomyopathy defined as appearance of ventricular dysfunction LVEF \<45% or admission due to heart failure.

    12 months

Secondary Outcomes (11)

  • Change in end-systolic volume.

    12 Months

  • Correction of septal flash.

    12 Months

  • Incidence of new onset of atrial fibrillation.

    12 Months

  • Hospitalization due to heart failure.

    12 Months

  • New York Heart Association functional classification.

    12 Months

  • +6 more secondary outcomes

Study Arms (2)

Conventional stimulation

ACTIVE COMPARATOR

An electrode (in the apical or septal portion) will be implanted at the discretion of the implanter physician. Parameters of (sensing, impedance and threshold) will be measured as is usually done in our center.

Device: Pacemaker implantation and conventional cardiac pacing

Physiological stimulation

ACTIVE COMPARATOR

Pacing the his-purkinje system.

Device: Conduction system pacing implant

Interventions

Right ventricular lead was placed to get his bundle or left bundle branch.

Physiological stimulation

Patients will have the pacemaker implanted in the electrophysiology laboratory. Electrode will be implanted (in the apical or septal portion) according to the criteria of the implanting physician.

Conventional stimulation

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The patient must be ≥ 18 years of age.
  • The patient must indicate their acceptance to participate in the study by signing an informed consent document.
  • Patients with EF\> 50% and indication for pacemaker implantation due to atrial-ventricular block according to current clinical guidelines.

You may not qualify if:

  • Inability to understand and sign the informed consent.
  • Patients with severe comorbidities and life expectancy \<1 year.
  • Patients with severe cognitive impairment or other comorbidities resulting in dependence for basic activities of daily life.
  • Patients who cannot come to our center to carry out the follow-up of the study.
