July 29, 2026 updated by: HUINNO Co., Ltd

Evaluation the Lightweight ECG Monitoring System Based on Al as a Telemetry ECG Monitoring System

This study aims to evaluate the clinical applicability of the AI-based lightweight ECG monitoring system (MEMO Patch Plus) as a telemetry ECG monitoring system in patients undergoing cardiac surgery. Participants will wear the MEMO Patch Plus for at least 48 hours and up to 168 hours after transfer from the intensive care unit to the general ward. The study will evaluate real-time ECG transmission, arrhythmia detection, device usability, and safety to generate preliminary evidence supporting future clinical studies.

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

Participants who provide written informed consent and meet all eligibility criteria will be enrolled in this prospective, single-arm study.

After transfer from the intensive care unit to the general ward, participants will wear the MEMO Patch Plus for continuous electrocardiographic (ECG) monitoring for a minimum of 48 hours and up to 168 hours. During the study period, the MEMO Patch Plus will continuously transmit ECG data to the monitoring system, allowing real-time remote monitoring by healthcare professionals. Clinical information related to arrhythmia detection, ECG transmission performance, and device operation will be collected throughout the monitoring period.

The primary outcome is the real-time ECG transmission rate. Secondary outcomes include the arrhythmia detection rate, device usability assessed by participants using a questionnaire, and safety assessed by device-related adverse events, including skin irritation. The results of this exploratory study will be used to evaluate the clinical applicability of the MEMO Patch Plus as a telemetry ECG monitoring system and to provide preliminary evidence for future clinical studies.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients who voluntarily decide to participate in this clinical study and provide written informed consent

Exclusion Criteria:

  • Patients younger than 19 years of age or 80 years of age or older
  • Pregnant or lactating women

Experimental: Remote MEMO Patch Plus Monitoring
Participants wear the MEMO Patch Plus after transfer from the intensive care unit to the general ward for continuous telemetry electrocardiographic (ECG) monitoring. The device is worn for a minimum of 48 hours and up to 168 hours, during which ECG data are continuously transmitted to the monitoring system for real-time remote monitoring. The study evaluates the clinical applicability of the MEMO Patch Plus by assessing the real-time ECG transmission rate, arrhythmia detection rate, participant-reported device usability, and device-related safety.
Device: MEMO Patch
The MEMO Patch Plus is a wearable adhesive ECG monitoring device for continuous cardiac rhythm monitoring. The device continuously acquires single-channel ECG signals and wirelessly transmits the data to a remote monitoring system, enabling real-time ECG monitoring and arrhythmia detection by healthcare professionals. The device is intended for continuous cardiac rhythm monitoring in hospitalized patients.
Other Names:
  • Adhesive ECG Patch

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
Real-time ECG Transmission Rate
Time Frame: During continuous ECG monitoring (minimum 48 hours to maximum 168 hours)
The real-time ECG transmission rate of the MEMO Patch Plus will be evaluated during the monitoring period. The transmission rate is defined as the proportion of successfully transmitted ECG data relative to the total monitoring time.
During continuous ECG monitoring (minimum 48 hours to maximum 168 hours)

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
Arrhythmia Detection Rate
Time Frame: End-of-study visit (7 to 30 days after hospital discharge)
The arrhythmia detection rate of the MEMO Patch Plus will be evaluated during the monitoring period based on clinically identified arrhythmia events.
End-of-study visit (7 to 30 days after hospital discharge)
Device Usability Questionnaire Score
Time Frame: Visit 3 (48 to 168 hours after device application)
Device usability will be evaluated using a participant-completed usability questionnaire after completion of the monitoring period. The questionnaire uses a 5-point Likert scale, with scores ranging from 1 to 5. Higher scores indicate better device usability.
Visit 3 (48 to 168 hours after device application)
