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.

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.
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.
