Feasibility and Usability of a Chest-Strap Ambulatory ECG Monitor in Active Individuals in Comparison With a Traditional Ambulatory ECG Patch Monitor (MoMe ARC)
What this study is about
The purpose of this research is to compare the standard ambulatory ECG monitor, the MoMe ARC, against Fourth Frontier's "Frontier X Plus". This device is an FDA-Cleared chest-strap-based ECG wearable that provides an alternative modality to capture ambulatory ECG rhythm changes.
View original scientific description
The purpose of this research is to compare the standard ambulatory ECG monitor, the MoMe ARC, against Fourth Frontier's "Frontier X Plus". This device is an FDA-Cleared chest-strap-based ECG wearable that provides an alternative modality to capture ambulatory ECG rhythm changes.
Interventions
DEVICE
Frontier X Plus chest-strap ECG device
The Frontier X Plus is a chest-strap-based wearable ECG device with embedded dry electrodes and a sensor that captures, stores, analyzes, and transmits ECG data through a mobile application and cloud-based platform for subsequent review.
DEVICE
MoMe ARC ambulatory ECG monitor
The MoMe ARC monitor will be used as the traditional ambulatory ECG comparator and processed according to standard clinical workflows.
Primary outcome measures
Concordance of Symptomatic Triggered Events Between Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Concordance will be assessed for symptomatic triggered events. Results will be reported as the number of symptomatic triggered event findings for which the Frontier X Plus and MoMe ARC reports are in agreement.
Concordance of Ventricular Tachycardia Episodes Greater Than 3 Beats Detected by Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Concordance will be assessed for ventricular tachycardia episodes greater than 3 beats. Results will be reported as the number of ventricular tachycardia episode findings for which the Frontier X Plus and MoMe ARC reports are in agreement.
Concordance of Supraventricular Tachycardia Episodes Greater Than 3 Beats Between Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Concordance will be assessed for supraventricular tachycardia episodes greater than 3 beats. Results will be reported as the number of supraventricular tachycardia episode findings for which the Frontier X Plus and MoMe ARC reports are in agreement.
Total Time in Atrial Fibrillation Detected by Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Total time in atrial fibrillation will be assessed for each device and reported as the cumulative duration of atrial fibrillation detected during the concordant monitoring period.
Concordance of Premature Atrial Contraction Counts Between Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Concordance will be assessed for premature atrial contraction counts. Results will be reported as the number of premature atrial contraction count findings for which the Frontier X Plus and MoMe ARC reports are in agreement.
Concordance of Premature Ventricular Contraction Counts Between Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Concordance will be assessed for premature ventricular contraction counts. Results will be reported as the number of premature ventricular contraction count findings for which the Frontier X Plus and MoMe ARC reports are in agreement.
Atrial Fibrillation Burden Detected by Frontier X Plus and MoMe ARC
Time frame: 24 hours
Automated Holter-style reports generated from the Frontier X Plus device will be compared with MoMe ARC reports. Atrial fibrillation burden will be assessed for each device and reported as the percentage of the concordant monitoring period during which atrial fibrillation was detected.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
