Trial summary

His-Ventricle (HV) measurement is only obtained invasively using transvenous catheters. This kind of procedure is routinely performed but some risks of complication exist. HV interval prolongation is correlated with increased risk of occurrence of complete atrioventricular block which could lead to syncope or cardiac… Read more about this study

About this study

His-Ventricle (HV) measurement is only obtained invasively using transvenous catheters. This kind of procedure is routinely performed but some risks of complication exist. HV interval prolongation is correlated with increased risk of occurrence of complete atrioventricular block which could lead to syncope or cardiac sudden death. A new non invasive, high density and high fidelity system (BioSemi, BioSemi B.V., Amsterdam, Netherlands) can theorically collect such electrophysiological signal using a signal averaging acquisition method. We want to assess the possibility of non invasive HV interval measurement using this new device.

What participants receive

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

  • Electrophysiological explorationProcedure or surgery

    Electrophysiological exploration is performed, as part of the routine care, after the Biosemi high density ECG, the same day or maximum 4 days later. It is performed in interventional rhythmology room, under fluoroscopic control. After local anesthesia, one or more introducers are placed in the femoral vein allowing the introduction of catheters. These catheters allow recording of the HV interval

  • ECG BiosemiDevice

    Non invasive ECG monitoring for HV measurement using high density Biosemi device. This device use 256 skin electrodes. At the same time and with the same system, a chest pressure sensor can record the patient's breathing movements.

What is being measured

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

  1. Measurement of HV interval correlation by the intra-class correlation coefficient

    The correlation of the HV interval obtained using the 2 different methods, is measured by a correlation coefficient

    Measured: Day 0

  2. Measurement of HV interval correlation by graphical representation

    The correlation of the HV interval obtained using the 2 different methods, is measured by a graphical representation of Bland and Altman

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

A study testing Electrophysiological exploration and ECG Biosemi in people with Cardiac Electrophysiology and Electrocardiogram, run by University Hospital, Bordeaux at 1 site in France.

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 1 inclusion and 2 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 22 Feb 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 France. 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?

Measurement of HV interval correlation by the intra-class correlation coefficient (time frame: Day 0). 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?
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 22 Feb 2022.
