Home-based Outpatient Multicenter Evaluation Using Electrocardiogram (HOME-ECG) (HOME-ECG)

March 21, 2026 updated by: Chin Lin, National Defense Medical Center, Taiwan

Prospective Multicenter Validation of a Home-Based Artificial Intelligence Enabled Single-Lead Electrocardiogram for Detecting Low Ejection Fraction and Structural Heart Disease

This prospective multicenter observational study will validate the accuracy of a previously developed artificial intelligence-enabled single-lead electrocardiogram (AI-ECG) model for identifying low ejection fraction and other structural heart disease phenotypes. Adult participants receiving a model-compatible single-lead electrocardiogram (ECG) (Apple Watch and QOCA ECG102D) and transthoracic echocardiography at five hospitals in Taiwan will be enrolled between March 1, 2026 and June 30, 2026. Model predictions will be compared with echocardiographic reference standards obtained within 30 days after the index ECG.

Intervention / Treatment

Intervention / Treatment

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Consecutive adult participants undergoing model-compatible single-lead ECG acquisition and paired echocardiographic assessment at five participating hospitals (Taipei Medical University WanFang Hospital; Far Eastern Memorial Hospital; Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation; Chi Mei Medical Hospital; and China Medical University Hospital) in Taiwan during the prospective enrollment period.

Description

Inclusion Criteria:

  • Age 20 years or older
  • Single-lead ECG recorded using a study-compatible device
  • Ability to comply with study procedures and, when applicable, provide informed consent according to local institutional review board (IRB) requirements
  • No transthoracic echocardiography performed within 90 days before the index ECG

Exclusion Criteria:

  • ECG signal quality insufficient for prespecified AI analysis
  • No transthoracic echocardiography available within 30 days after the index ECG
  • Echocardiography unavailable or technically inadequate for determining left ventricular ejection fraction (EF)

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Prospective Validation Cohort
Adults enrolled at participating hospitals who undergo model-compatible single-lead ECG acquisition and reference transthoracic echocardiography for prospective validation of AI-ECG models for low ejection fraction and structural heart disease.
Diagnostic test: Single-Lead ECG Acquisition [Apple Watch and QOCA ECG102D]
A single-lead Lead-I ECG recorded using a device compatible with the prespecified AI-ECG pipeline and analyzed offline by the locked AI model.

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
Area Under the Receiver Operating Characteristic Curve for Detection of Low Left Ventricular Ejection Fraction
Time Frame: 30 days
AUC with 95% confidence interval for detection of low EF, defined as echocardiographic LVEF ≤40%, by the pre-specified AI-enabled single-lead ECG model.
30 days
Sensitivity, Specificity, Positive Predictive Value, and Negative Predictive Value for Low EF Detection at the Pre-specified Operating Threshold
Time Frame: 30 days
Diagnostic operating characteristics of the locked AI model for low EF at the pre-specified threshold.
30 days

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
Positive Predictive Value and Negative Predictive Value for Structural Heart Disease at the Pre-specified Operating Threshold
Time Frame: 30 days
Prevalence of structural heart disease in patients identified as positive and negative by AI-ECG for detecting low EF, including left atrial enlargement, valvular heart disease, pulmonary hypertension, left ventricular hypertrophy, etc.
30 days
Difference in All-Cause Mortality Risk at the Pre-specified Operating Threshold
Time Frame: 90 days
All-cause mortality risk in patients identified as positive and negative by AI-ECG for detecting low EF.
