About this study
Official title: Investigator-initiated Trial to Evaluate the Performance and Utility of a Single-lead Electrocardiogram Patch-based Telemetry System in Patients Requiring In-hospital Telemetry Electrocardiogram Monitoring During Hospitalization
"This investigator-initiated, prospective, single-center clinical study evaluates the performance and clinical utility of a single-lead electrocardiogram (ECG) patch-based telemetry system for hospitalized patients who require in-hospital telemetry ECG monitoring. The system integrates real-time centralized surveillance (MEMO-Cue) with post-hoc analytic review (MEMO-Care) using ECG signals recorded by the MEMO Patch M, aiming to enable timely recognition of clinically important arrhythmias and to inform treatment decisions under routine inpatient conditions.
Adults (≥19 years) indicated for continuous ECG monitoring during admission are enrolled after written informed consent, with a planned sample size of 100 to yield approximately 90 evaluable participants (10% anticipated dropout). The design does not include randomization or blinding. Study procedures include a screening visit (eligibility and baseline data), an inpatient monitoring period of at least 12 hours and up to 8 days with simultaneous MEMO-Cue monitoring and MEMO Patch M recording, and an end-of-visit assessment when MEMO-Care analytic results become available. Concomitant therapies deemed clinically necessary are permitted and documented, and adverse events are prospectively assessed.

Clinical utility endpoints quantify care impact and timeliness: (1) rate of treatment plan changes (e.g., initiation or modification of anticoagulants or antiarrhythmic drugs, cardioversion scheduling, device implantation, or other actions); (2) time to recognition (days) of major arrhythmias-atrial fibrillation (AF), ventricular tachycardia (VT), pause, ventricular premature complex (VPC), and supraventricular tachycardia (SVT)-based on MEMO-Cue alarms or MEMO-Care results with objective confirmation; (3) reduction ratio in recognition time when identified earlier by MEMO-Cue versus MEMO-Care; and (4) proportion of participants with shortened recognition time by MEMO-Cue.
Clinical performance endpoints assess detection characteristics and agreement between MEMO-Cue alarms and MEMO-Care findings: (1) clinical sensitivity (true positive / [true positive + false negative]); (2) precision, i.e., positive predictive value (true positive / [true positive + false positive]); and (3) positive concordance rate (proportion of MEMO-Care-detected arrhythmias alerted by MEMO-Cue). Safety is captured as treatment-emergent adverse events after device application, including device-related skin reactions, detachment, or signal dropouts, with severity graded per NCI-CTCAE v5.0 and relationship to device recorded.
By characterizing real-time patch-based telemetry alongside analytic review and its influence on diagnostic timing and management, the study aims to generate practical evidence supporting feasibility, reliability, and workflow compatibility of single-lead patch telemetry for in-hospital ECG monitoring.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MEMO-Cue-based telemetry monitoringDevice

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Clinical decision change rate based on MEMO-Cue monitoring (time frame: From baseline (start of MEMO-Cue monitoring) to end of monitoring period, up to 8 days during hospitalization.). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2025.
