研究概览
简要总结
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.
详细描述
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:
