November 16, 2025 updated by: Chin Lin, National Defense Medical Center, Taiwan

Leveraging AI-ECG Technology for Early Notification and Tracking of AF Development: a Randomized Control Trial

Our study aimed to use an AF-predict AI-ECG alert system to help physicians identify patients who need to wear a continuous cardiac rhythm monitor for new diagnoses of atrial fibrillation (AF), atrial flutter (AFL), or atrial arrhythmia with high AF risk, including premature atrial complexes (PAC) ≥ 500/24hr, burst PACs > 20 beats, non-sustained AF/AFL.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
14726

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients in the inpatient department or the outpatient department
  • Patients need to have at least one electrocardiogram within one year

Exclusion Criteria:

  • Diagnosis of atrial fibrillation/atrial flutter
  • History of atrial fibrillation/atrial flutter catheter ablation
  • Patients with cardiac implantable electronic devices
  • Any documented electrocardiogram showed atrial fibrillation/atrial flutter and pacing rhythm
  • History of received rhythm control medications for atrial arrhythmia, including Class I and Class III antiarrhythmic drugs

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: AF-predict AI-ECG alert system
All the patients' ECGs will receive AF-predict AI-ECG analysis. According to the AI-ECG analysis results, those with at least one high-risk ECG within one year will be called back and asked to undergo a continuous cardiac rhythm monitor for up to 7 days. Otherwise, the physicians can review the AI-ECG analysis results for all the patients in the intervention group.
Other: AF-predict AI-ECG alert system guided management
AF-predict AI-ECG alert system
No Intervention: Standard of care
Patients will receive the standard care, and their ECGs will not be analyzed by AI-ECG before the end of the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Latent atrial fibrillation
Time Frame: Within 90 days after enrollment.
The primary outcome, latent atrial fibrillation, is a composite of new diagnoses of AF/AFL, atrial arrhythmia with high AF risk, including PACs ≥ 500/24hr, burst PACs > 20 beats, and non-sustained AF/AFL, within 90 days after enrollment. The results will be demonstrated as the rate of diagnoses of latent atrial fibrillation.
Within 90 days after enrollment.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Antiarrhythmic treatment
Time Frame: Within 180 days after enrollment.
Antiarrhythmic treatment may include newly prescribed beta-blockers or non-dihydropyridine calcium channel blockers, class Ia, Ic, and III antiarrhythmic drugs, and catheter ablation. Physicians can determine whether a patient requires antiarrhythmic treatment through clinical practice. The outcome is the rate of initiation of antiarrhythmic treatment.
Within 180 days after enrollment.
90-days New diagnoses of atrial fibrillation/atrial flutter
Time Frame: Within 90 days after enrollment.
New diagnoses of atrial fibrillation or atrial flutter are defined as those documented by a 12-lead electrocardiogram or by continuous cardiac rhythm monitoring for ≥ 30 seconds. The result will be presented as the rate of new diagnoses of atrial fibrillation or atrial flutter.
Within 90 days after enrollment.
Atrial arrhythmia with high AF risk
Time Frame: Within 90 days after enrollment.
Atrial arrhythmia with high AF risk is defined by the following criteria: premature atrial complexes more than 500 beats in 24 hours as recorded by a continuous cardiac rhythm monitor; burst premature atrial complexes exceeding 20 beats as documented in a continuous cardiac rhythm monitor or a 12-lead electrocardiogram, or documented non-sustained AF/AFL in either a continuous cardiac rhythm monitor or a 12-lead electrocardiogram. The result will be presented as the rate of diagnoses of atrial arrhythmia with high AF risk.
Within 90 days after enrollment.
