Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 22 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: The study will include two cohorts of subjects: 1. Cohort 1 will include subjects with no known history of AFib and are in normal sinusn rhythm at time of screening. 2. Cohort 2 will include subjects with known persistent or permanent or chronic AFib who are in AFib at the time of screening. The study will enroll equal subjects with and without a known diagnoiss of AFib into two separate cohorts. A total of 602 subjects will be recruited (301 for SR cohort and 301 for AFib cohort). The following age and gender enrollment targets will be adhered to during subject recruitment: 1. A minimum of 20% of subjects in both cohorts will be enrolled in each of the age categories of 55 to 64, and ≥65 years, and a minimum of 10% of subjects in both cohorts in the age category of <55 years. 2. At least 40% of subjects in Cohort 1 will be female. At least 20% of subjects in Cohort 2 will be female.

Who may be able to join

  • Willing and able to participate in the study procedures as described in the consent form
  • Individuals who are 22 years of age and older at time of screening
  • Able to communicate effectively with and follow instructions from the study staff
  • Subjects enrolled into Cohort 1 must have no known medical history of AFib and in normal sinus rhythm at the time of screening.
  • Subjects enrolled into Cohort 2 must have a known diagnosis of persistent or permanent AFib and be in AFib at the time of screening.

Who cannot join

  • Physical disability that precludes safe and adequate testing
  • Mental impairment as determined by the Investigator
  • Pregnant women at the time of the screening visit.
  • Subjects with any Medical History, Physical exam, vital sign or any other study procedure finding/assessment that in the opinion of the investigator could compromise subject safety during study participation or interfere with the study integrity and/or the accurate assessment of the study objectives. This includes patients with known untreated medical conditions that are considered clinically significant by the Investigator, such as but not limited to significant anemia, important electrolyte imbalance and untreated or uncontrolled thyroid disease. Physical exam limitations include but not limited to open wound(s) on the wrist and forearm where the subject will be wearing the watch.
  • Any history of wrist surgery with scarring in the area of the sensor location on the wrist where the subject will be wearing the watch.
  • Vital signs measurement, medical history, or physical exam finding that makes the subject inappropriate for participation according to the Investigator.
Show all 11Show fewer
  • Tattoos or moles in the area of the sensor location on the wrist where the subject will be wearing the watch.
  • Skin conditions on either wrist that would preclude subject from wearing watch on either wrist. Severe symptomatic (or active) overly dry/injured skin, skin disorders, or allergic skin reactions such as eczema, rosacea, impetigo, dermatomyositis or allergic contact dermatitis on wrist and locations where the electrodes will be placed (e.g. chest, forearms, stomach), as determined by the investigator.
  • Known allergy or significant sensitivity to medical adhesives, isopropyl alcohol, or ECG patch.
  • Clinically significant hand tremors as judged by the Investigator.
  • Subjects with implanted cardiac devices such as a Pacemaker or an automated Implantable Cardioverter - Defibrillator.

About this study

Official title: Clinical Validation of the Electrocardiogram Measurement and Atrial Fibrillation Detection Function of a Wearable Smartwatch

Atrial fibrillation (AFib) is a common type of cardiac arrhythmia in clinical practice, affecting millions of people worldwide. Early detection and treatment of atrial fibrillation are crucial in preventing serious complications such as stroke and heart failure. In recent years, with the flourishing development of wearable devices and mobile technology, electrocardiogram (ECG) measurement applications embedded in smartwatches have gradually become a non-invasive and convenient method for heart rate monitoring. However, the accuracy of these devices has not yet been fully determined. This study aims to verify the ECG measurement and atrial fibrillation detection function of the ASUS Blood Pressure Monitor/Oximeter/ECG Monitor. The accuracy of the ECG application in detecting atrial fibrillation and measuring ECG will be evaluated by comparison with standard 12-lead ECGs.

Read the detailed description

This study plans to recruit 602 adults over the age of 22. All participants will undergo heart rate measurements using both the smartwatch ECG application and the 12-lead ECG. The heart rate measurement using the ECG application will be operated by the participants themselves under the guidance of the testing personnel. The 12-lead ECG will be operated by trained medical professionals. The results of the heart rate measurement from both devices will be recorded synchronously, and the consistency of heart rate interpretation and ECG waveforms between the smartwatch ECG application and the 12-lead ECG measurement will be compared to verify the accuracy of the ECG application.

What participants receive

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

  • ASUS Blood Pressure Monitor/Oximeter/ECG MonitorDevice

    The ASUS Blood Pressure Monitor/Oximeter/ECG Monitor analyzes data collected by the integrated electrical sensors on a ASUS Vivowatch to generate an ECG waveform similar to a Lead I, calculate average heart rate, and provide a rhythm classification to the user for a given 30 second session. When a user opens the ECG App while wearing the ASUS VivoWatch on one wrist and places the finger of the opposite hand on the digital crown, they are completing the circuit across the heart which begins a recording session.

    Once the recording session is complete, the ECG App performs signal processing, feature extraction and rhythm classification to generate a session result.

What is being measured

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

  1. Sensitivity and specificity of the ECG App algorithm

    Sensitivity and specificity of the ECG App algorithm in detecting AFib compared with physician-adjudicated 12-lead ECG will be calculated.

    Measured: One day visit

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Taipei Medical University Hospital.

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 5 inclusion and 11 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 24 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Sensitivity and specificity of the ECG App algorithm (time frame: One day visit). 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 24 Nov 2023.
