About this study

The purpose of the study is to confirm the Garmin ECG (electrocardiogram) software algorithm can detect and classify atrial fibrillation and normal sinus rhythm on single lead ECG data derived from a Garmin wrist-worn, consumer device. The study will also confirm the software's ability to create a Lead I ECG that is clinically equivalent to a reference device. The Garmin ECG software is not a diagnostic system and is intended for informational purposes only.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ElectrocardiogramDiagnostic test

    Simultaneous assessment of the heart rhythm determined from a 12-lead ECG and the Garmin ECG software algorithm heart rhythm classification on single-lead ECG data derived from the wearable device. All participants will record three simultaneous 12-lead and single-lead ECGs.

Study groupRoleWhat they receive
Atrial fibrillation (AF)OtherPatients with a known history of AF who are in AF at the time of study screening.
Receives: Diagnostic Test: Electrocardiogram
Normal Sinus Rhythm (SR)OtherPatients with no known diagnosis of AF or other arrhythmia
Receives: Diagnostic Test: Electrocardiogram

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Specificity of rhythm classification

    Number of participants with a SR software rhythm classification in agreement with a physician's interpretation of heart rhythm based on gold standard 12-lead ECG

    Measured: 1 Day

  2. Sensitivity of rhythm classification

    Number of participants with an AF software rhythm classification in agreement with a physician's interpretation of heart rhythm based on gold standard 12-lead ECG

    Measured: 1 Day

Secondary outcomes (2)
  1. Number of ECGs that pass a visual overlay

    Number of participants with software's ability to produce a clinically equivalent waveform in agreement to a gold standard Lead I reference

    Measured: Day 1

  2. Difference in R-wave amplitudes between the software and gold standard reference

    Number of participants with software's ability to produce a clinically equivalent waveform in agreement to a gold standard Lead I reference

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing Electrocardiogram in people with Atrial Fibrillation, run by Garmin International at 6 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Specificity of rhythm classification (time frame: 1 Day). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Feb 2022.
