Feasibility and Usability of a Chest-Strap Ambulatory ECG Monitor in Active Individuals in Comparison With a Traditional Ambulatory ECG Patch Monitor (MoMe ARC)

August 14, 2026 updated by: Elizabeth H. Dineen, Mayo Clinic
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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

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.

Description

Inclusion Criteria:

  • Adult participants (>22 years; Frontier X is approved for use in this age group) who participate in >4 days a week of >150 minutes total per week of moderate to high intensity exercise who were prescribed a ambulatory ECG monitor for clinical purposes for 24 hours or more.
  • Patients must agree to wear the Frontier X monitor for the prescribed duration and use the Frontier X Plus application

Exclusion Criteria:

  • Current use of Implanted Cardiac Devices
  • Pregnancy
  • Known allergies to any of the materials listed in the "List of Patient-Contacting Materials"
  • Presence of skin injuries or broken skin in the area where the chest strap is worn
  • Inability to use a compatible mobile device required for the operation of the study device
  • Any cognitive or physical limitations that, in the opinion of the investigator, limits the participant's ability to fully follow study procedures
  • Medical restrictions on exercise for safety including cardiac, orthopedic or other relevant past medical history

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Adults Undergoing Ambulatory ECG Monitoring
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
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
