An observational study in Cardiac Arrhythmia, sponsored by Mayo Clinic. Recruiting at 3 sites in United States. Open to participants aged 22 Years and older. Per ClinicalTrials.gov, last updated 2026-09-17.
Sponsored by Mayo Clinic · Observational
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.
Active adults older than 22 years who participate in moderate- to high-intensity exercise at least 4 days per week and more than 150 minutes per week total, and who have been prescribed ambulatory ECG monitoring for clinical purposes for 24 hours or more.
Exclusion Criteria:
Participants prescribed clinical ambulatory ECG monitoring will wear the Frontier X Plus chest-strap ECG device simultaneously with the MoMe ARC traditional ambulatory ECG monitor during their prescribed monitoring period and typical daily activities, including exercise.
Device: Frontier X Plus chest-strap ECG device · Device: MoMe ARC ambulatory ECG monitor
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.
The MoMe ARC monitor will be used as the traditional ambulatory ECG comparator and processed according to standard clinical workflows.
Concordance of Symptomatic Triggered Events Between Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
Concordance of Ventricular Tachycardia Episodes Greater Than 3 Beats Detected by Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
Concordance of Supraventricular Tachycardia Episodes Greater Than 3 Beats Between Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
Total Time in Atrial Fibrillation Detected by Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
Concordance of Premature Atrial Contraction Counts Between Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
Concordance of Premature Ventricular Contraction Counts Between Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
Atrial Fibrillation Burden Detected by Frontier X Plus and MoMe ARC
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.
Time frame: 24 hours
