About this study

Official title: Electrical and Mechanical Activation in PAcing The His Bundle Conduction sYstem: EMPATHY Study

In recent years, the finding of long-term deleterious effects of right ventricular pacing (RVP) has led to an ongoing search for alternative pacing sites such as His bundle stimulation. The depolarization of the ventricles through the His-Purkinje cardiac conduction system seems to represent an ideal physiological approach to ventricular pacing, capable of engaging the normal conduction pathways and determining synchronous ventricular activation. However, there are still no clinical studies that have evaluated the electromechanical functions of the left ventricle with His bundle pacing (HBP) identified after electroanatomical reconstruction with 3D mapping system. Investigators aimed to compare the electromechanical effects on left ventricle of HBP, compared to RVP stimulation and to spontaneous rhythm of each patient.

Read the detailed description

Patients with indication for permanent pacemaker implantation were included in the study. The stimulation lead was positioned at the level of the His bundle after complete electroanatomical reconstruction of the atrium and right ventricle with 3D mapping system; a second backup lead was eventually placed in the right ventricle. Within 24 hours after implantation, each patient underwent 12-lead ECG and a complete echocardiographic examination in the different pacing modalities (HBP, RVP and patient's spontaneous rhythm) focused on the evaluation of biventricular systo-diastolic function, speckle-tracking and myocardial work of the left ventricle.

What is being measured

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

  1. Evaluate the electrocardiographic differences of HBP, obtained by electroanatomical reconstruction with 3D mapping system, compared to the RVP and the patient's spontaneous rhythm.

    Measurement of QRS width (msec) in 12-lead electrocardiogram

    Measured: 24 hours after implantation

  2. Evaluate the echocardiographic differences of HBP, obtained by electroanatomical reconstruction with 3D mapping system, compared to the RVP and the patient's spontaneous rhythm.

    Transthoracic echocardiogram measurement such as left ventricular systolic function (%), left ventricular Global Longitudinal Strain (GLS %), tissue doppler and severity of any valve disease

    Measured: 24 hours after implantation

Questions about this trial

What is this clinical trial studying?

An observational study of Pacemaker DDD and His Bundle Pacing, run by University Hospital of Ferrara at 1 site in Italy.

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 3 inclusion and 4 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: finished, as of the sponsor's last update on 30 Nov 2022. 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 Italy. 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. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Evaluate the electrocardiographic differences of HBP, obtained by electroanatomical reconstruction with 3D mapping system, compared to the RVP and the patient's spontaneous rhythm. (time frame: 24 hours after implantation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05222672, which also lists 1 linked publication.

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 30 Nov 2022; AzTrials last refreshed its copy on 29 Oct 2026.
