AI-Based Cardiac Analysis Using 12-Lead and 1-Lead ECG

October 28, 2026 updated by: Yong-Soo Baek, Inha University Hospital

Prospective Observational Comparative Pilot Study to Evaluate Performance of an AI-based Cardiac Disease Analysis Algorithm Using Standard 12-lead ECG and Single-lead ECG Data

This pilot study is designed to evaluate the clinical performance and utility of the SmartECG-EF software in patients undergoing evaluations at Inha University Hospital. The primary objective is to assess how effectively the device assists clinicians in evaluating cardiac function and related clinical parameters. The study will prospectively enroll eligible participants to gather real-world clinical data, contributing to enhanced diagnostic accuracy and patient management.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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.

Detailed Description

This is a prospective, single-center pilot study conducted at Inha University Hospital to evaluate the clinical performance and feasibility of the SmartECG-EF software. Eligible participants will undergo standard clinical evaluations alongside the investigational device assessment. The study aims to investigate the diagnostic utility and operational workflow of integrating the software into routine clinical practice. Data regarding clinical parameters, primary and secondary outcome measures, and any device-related adverse events will be systematically collected and analyzed to assess safety and efficacy.

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

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients visiting Inha University Hospital who undergo standard 12-lead and additional 1-lead ECG evaluations for cardiac assessment.

Description

Inclusion Criteria:

  • Written informed consent provided voluntarily by the subject
  • Age ≥ 19 years
  • Patients who undergo standard 12-lead ECG measurement during the study period
  • Subjects with sinus rhythm on ECG at the time of examination
  • Subjects available for additional 1-lead ECG measurement during the same visit

Exclusion Criteria:

  • Subjects deemed inappropriate or unlikely to comply with the study requirements by the investigator
  • Patients with atrial fibrillation or atrial flutter on ECG at the time of examination
  • Patients with pacing rhythm due to a pacemaker
  • Subjects with severe tremor, uncooperativity, or skin conditions that make 1-lead ECG measurement difficult
  • Subjects whose additional study measurements would delay standard medical care due to a critical medical condition
  • Withdrawal of consent or refusal to agree to personal information usage
  • ECG with sub-standard quality (unanalyzable noise, lead disconnection, etc.; note: unanalyzable rate evaluation can be recorded separately)

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.
SmartECG-EF Evaluation Group

Patients undergoing prospective evaluation using the SmartECG-EF software for cardiac function assessment and ECG-based parameter analysis at Inha University Hospital.
Device: SmartECG-EF

The SmartECG-EF software is used to analyze 12-lead and 1-lead electrocardiogram (ECG) data to evaluate cardiac function, including left ventricular systolic dysfunction (LVSD), heart failure indicators, and related arrhythmic parameters.

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
Correlation and Agreement between 12-Lead and 1-Lead AI Scores
Time Frame: Day 1

To evaluate the correlation (using Pearson or Spearman correlation coefficients), agreement (ICC using absolute agreement, two-way random model), and Bland-Altman analysis (mean difference and 95% limits of agreement) between 12-lead and 1-lead based AI scores.
Day 1

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
Area Under the ROC Curve (AUC-ROC) of AI scores
Time Frame: Baseline

To assess the AUC-ROC of 1-lead and 12-lead based AI results against disease-specific reference standards, including heart failure, left ventricular systolic dysfunction (LVSD), and arrhythmic parameters.
Baseline
Sensitivity and Specificity of AI scores
Time Frame: baseline

To assess sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 1-lead and 12-lead based AI results against disease-specific reference standards, including heart failure, left ventricular systolic dysfunction (LVSD), and arrhythmic parameters.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
