4-electrode ECG (DigitalCardio®) vs Standard 10-electrode ECG: Evaluating Ease of Use and Recording Quality (FAST-ECG)

9. september 2026 opdateret af: Clinique Bizet

The goal of this clinical trial is to compare the time required to record a complete Electrocardiogram (ECG) trace using the DigitalCardio (CardioSecur®) tablet device versus a standard 12-lead ECG device in eligible patients.

The main questions it aims to answer are:

Is there a difference in diagnostic recording time (in minutes) between the DigitalCardio tablet and a standard ECG machine? How do the two devices compare in terms of trace quality (including QRS duration, QT interval, frontal axis measurements, and missing/erroneous leads)? How satisfied are healthcare professionals with the CardioSecur® device?

Researchers will compare Group A (standard 10-electrode ECG followed by 4-electrode ECG) to Group B (4-electrode ECG followed by standard 10-electrode ECG) in a 1:1 randomized crossover design to evaluate recording efficiency and trace quality.

Participants will:

Complete an initial screening visit with the principal investigator to review eligibility criteria and sign the informed consent form.

Be randomly assigned (1:1 ratio) to either Group A or Group B. Undergo both ECG recording methods sequentially (a standard 10-electrode ECG and a 4-electrode ECG using the DigitalCardio tablet), while researchers measure the total time elapsed from electrode placement to obtaining a complete trace.

Studieoversigt

Detaljeret beskrivelse

This study is a randomized, crossover clinical trial designed to compare the efficiency, trace quality, and user satisfaction of a novel 4-electrode tablet-based Electrocardiogram (ECG) system (DigitalCardio / CardioSecur®) against a standard 12-lead (10-electrode) ECG device.

Background and Rationale

An electrocardiogram (ECG) is a fundamental diagnostic tool used to record the electrical activity of the heart. Conventional 12-lead ECGs require placing 10 individual electrodes on a patient's limbs and chest while the patient is lying down. While highly detailed, electrode placement and device setup can be time-consuming in clinical workflows. The DigitalCardio tablet system utilizes a simplified 4-electrode setup designed to streamline data acquisition without compromising diagnostic accuracy.

Study Design and Procedures

After an initial screening process led by the principal investigator, eligible participants receive detailed study information and provide written informed consent. Enrolled participants are then randomly assigned in a 1:1 ratio to one of two sequence groups to control for order effects:

*Group A:Undergoes standard 10-electrode ECG acquisition first, followed immediately by 4-electrode DigitalCardio acquisition.

Group B: Undergoes 4-electrode DigitalCardio acquisition first, followed immediately by standard 10-electrode ECG acquisition.

To maintain consistency, both ECG recordings for a given participant are performed by the same healthcare operator within a minimal time interval.

Key Measurements

  1. Diagnostic Time:Research staff record the exact time elapsed (in minutes) from the initiation of electrode placement to the successful capture of a complete ECG trace for both devices.
  2. Trace Quality and Concordance:Printed and anonymized ECG traces are submitted to independent evaluators. Evaluators independently assess trace quality based on standardized criteria, comparing automated measurements (frontal axis, median QRS duration, and QT interval) and counting any missing or erroneous leads.
  3. Healthcare Professional Satisfaction:Participating healthcare professionals complete a structured questionnaire evaluating user satisfaction and usability of the CardioSecur® device in routine practice.
