What participants receive

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

  • Monitoring with wearable (the tested device) and Holter ECG (eMotion Faros 90)Device

    Participants will use the wearable (the tested device) to record at least 2 minutes of photoplethysmography and 6-lead ECG. In addition, each subject will be monitored with synchronous ECG Holter monitoring (with eMotion Faros 90).

What is being measured

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

  1. Diagnostic accuracy of a wearable system for atrial fibrillation detection

    The wearable system comprises of two integrated components: a photoplethysmography (PPG) and a 6-lead ECG of the device. It works as described below.

    First, an automatic PPG algorithm will indicate whether atrial fibrillation is suspected. The rhythm assessment of PPG algorithm is based on pulse regularity.

    Next, a 6-lead ECG is acquired by the wearable. The rhythm assessment of ECG is based on P waves and regularity of QRS complexes. A diagnosis is made by independent cardiologists.

    The conclusion of a whole system comprising of both described methods will be compared with a gold standard multi-lead Holter ECG. This standard ECG is also evaluated by independent cardiologists.

    Measured: PPG will be assessed in 2 minutes. ECG will be assessed in up to 10 months.

Secondary outcomes (2)
  1. Diagnostic accuracy of PPG algorithm of the wearable for atrial fibrillation detection

    An automatic PPG algorithm will indicate whether atrial fibrillation is suspected. The rhythm assessment of PPG algorithm is based on pulse regularity. As a separate diagnostic tool it will be compared with a gold standard multi-lead Holter ECG which is assessed by independent cardiologists.

    Measured: 2 minutes.

  2. Diagnostic accuracy of a 6-lead ECG of the wearable for atrial fibrillation detection

    Independent cardiologists will assess the heart rhythm in a 6-lead ECG acquired by the wearable. As a separate diagnostic tool it will be compared with a gold standard multi-lead Holter ECG which is also assessed by independent cardiologists. The rhythm evaluation of ECG is based on P waves and regularity of QRS complexes.

    Measured: Up to 10 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Vilnius University at 1 site in Lithuania.

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 2 inclusion and 2 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 10 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Lithuania. 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?

Diagnostic accuracy of a wearable system for atrial fibrillation detection (time frame: PPG will be assessed in 2 minutes. ECG will be assessed in up to 10 months.). 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 10 Feb 2021.
