About this study

Official title: CART Phase 2 Study: Diagnostic Performance of a Ring-type Wearable Device Using Deep Learning Analysis of Photoplethysmographic Signals for Detecting Atrial Fibrillation

This study investigates diagnostic performance of a ring-type wearable device for detecting atrial fibrillation. This is a prospective cohort registry study began after the date of IRB approval and until 31th Dec. 2019. The eligible criteria are (1) those who admitted the institution for elective direct-current cardioversion of persistent atrial fibrillation, and (2) aged 19 years or more. The exclusion criteria are (1) those aged less than 19 years, (2) those who are not eligible to perform cardioversion by any reasons. This study aims to recruit 200 participants in total. The participants are required to record photoplethysmographic signals by the ring device in addition to routine procedures of direct-current cardioversion, hence, the study is at minimal risk.

  4. Sponsor: Sky Labs, Inc., Republic of Korea.
  5. The aim of the study: To evaluate diagnostic performance of a ring-type wearable device for detecting atrial fibrillation.
  6. Study period: From the date of IRB approval to 31th Dec. 2019.
  7. The size of study population: 200 participants
  8. The eligibility criteria: (1) Those with persistent atrial fibrillation (2) Those who admitted the institution for elective direct-current cardioversion (3) Those aged 19 years or more 9. The exclusion criteria: (1) Those with other forms of cardiac arrhythmias (2) Those aged less than 19 hears (3) Those who are not eligible to perform electrical cardioversion 10. Procedures of the study
  9. A participant is under the routine procedures of direct-current cardioversion.
  10. On admission, a participant is given with detailed information of the study.
  11. After the informed consent, the only additional procedure due to the study is recording photoplethysmographic signal by wearing a ring-type device.
  12. Recorded signals are evaluated without encompassing persornal information. 11. Financial benefits to the participants: None.

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Seoul National University Hospital at 1 site in South Korea.

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 3 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 18 Mar 2020. 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 South Korea. 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?

Results are not available in the source record.

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 performance (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04023188, which also lists 1 linked publication.

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 18 Mar 2020.
