About this study

Official title: His Bundle Pacing Versus Right Ventricular Pacing: a Randomized Crossover Study (His-PACE)

This study will randomize cross-over periods of 6 months of right ventricular pacing and His bundle pacing in patients with baseline left ventricular ejection fraction (LVEF)>40%. The primary outcome measure is LVEF.

Read the detailed description

Monocentric, randomized, double-blind comparative crossover clinical study.

Patients with a standard pacing indication with >20% ventricular pacing, with a baseline LVEF >40%, implanted with a functioning His bundle lead and a backup right ventricular lead, will be randomized to 6-months periods of right ventricular pacing and of His bundle pacing. The primary outcome is LVEF assessed by gated Equilibrium Radionuclide Angiography. Secondary outcomes are diastolic function, New York Heart Association (NYHA) functional class, quality of life, 6-minute walk test, heart failure hospitalisations and device electrical parameters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • His bundle pacingDevice

    Pacing with capture of the His bundle

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Left ventricular ejection fraction

    Assessed by gated Equilibrium Radionuclide Angiography

    Measured: 6 months

Secondary outcomes (7)
  1. Left ventricular peak filling rate (EDV/s)

    Assessed by gated Equilibrium Radionuclide Angiography

    Measured: 6 months

  2. NYHA functional class

    Investigator evaluation

    Measured: 6 months

  3. 6-minute walk test

    Investigator evaluation

    Measured: 6 months

  4. Quality of life measure by SF-36 questionnaire

    SF-36 questionnaire; 0-100 score (the higher the score, the better the quality of life)

    Measured: 6 months

  5. Right ventricular ejection fraction

    Assessed by gated Equilibrium Radionuclide Angiography

    Measured: 6 months

  6. Hospital admission for cardiovascular causes

    Number of days of admissions for cardiovascular causes

    Measured: 6 months

  7. Hospital admission for cardiovascular causes

    Duration in days of admissions for cardiovascular causes

    Measured: up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing His bundle pacing and Right ventricular pacing in people with Pacing-Induced Cardiomyopathy, run by University Hospital, Geneva at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 9 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Slow recruitment since the advent of left bundle branch area pacing). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Left ventricular ejection fraction (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Apr 2025.
