A recently completed three-phase clinical trial spearheaded by Zywie, Inc. has provided remarkable insights into the comparison of a novel test ECG device and a reference device. Healthy study participants were tasked to undergo three distinct evaluations aimed at better understanding the device's performance and signal quality over time. With these findings, clinical, regulatory, and quality teams in the medical device field can anticipate future innovations and regulatory submissions.
What Did Phase 1 Involve?
The first phase of this study focused on evaluating the test device's ECG data against that captured by a reference device, currently established as a reliable standard in the field. This comparison not only quantifies the performance of the test device but also ensures its data accuracy and reliability in real-world clinical settings. Healthy subjects participated to allow for controlled conditions, ensuring baseline readings free of confounding variables.
The goal of this phase was to confirm that the test device aligns with stringent regulatory requirements, establishing its viability for further clinical and commercial development.
Key Findings from the 10-Day Signal Quality Trial
Phase 2 of the study extended the scope to observe the signal quality of the test device over a prolonged 10-day period. This simulated real-world use case scenarios, evaluating how device adhesion, electrode performance, and overall durability affected data collection.
The results underscored the importance of consistent signal integrity in wearables over time, a critical factor in both diagnostic confidence and patient safety. Regulatory teams preparing MDR Annex XIV submissions may find these findings particularly relevant given the focus on clinical evidence of long-term use.
Variable Electrode Placement Evaluation
The third and final phase assessed the effects of varying ECG electrode placements on the test device's data output. Accurate electrode positioning is vital for ECG devices, and deviations can significantly impact diagnostic outcomes. This phase explored how the device performed under realistic conditions where perfect placement might not always be achieved.
The study demonstrated that the test device offers some resilience to placement variability, a feature that could enhance ease of use and adoption by healthcare providers.
