A Ring-type Wearable Device for Atrial Fibrillation

Status Active, not recruiting

Clinical Trial Summary

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.

Clinical Trial Description

1. Study title: Diagnostic Performance of a Ring-type Wearable Device Using Deep Learning Analysis of Photoplethysmographic Signals for Detecting Atrial Fibrillation.

2. Study type: Investigator initiated study.

3. Study design: Prospective observational cohort registry design.

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

1. A participant is under the routine procedures of direct-current cardioversion.

2. On admission, a participant is given with detailed information of the study.

3. After the informed consent, the only additional procedure due to the study is recording photoplethysmographic signal by wearing a ring-type device.

4. Recorded signals are evaluated without encompassing persornal information. 11. Financial benefits to the participants: None. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
