Experimental: Memo Patch continuous ECG strategy
Participants undergo continuous single-lead ECG monitoring with Memo Patch for up to 7 consecutive days and report symptom onset using a mobile messaging chatbot or paper diary.
|
Continuous single-lead ECG monitoring for up to 7 consecutive days.
Participants report the onset of symptoms using a mobile messaging chatbot or paper diary.
For each reported symptomatic episode, a 20-minute ECG segment extending from 10 minutes before to 10 minutes after the reported onset is available for review.
|
|
Aktiver Komparator: Hativ handheld ECG strategy
Participants use Hativ for 30 days and perform 10-second 6-lead ECG recordings at least twice daily and whenever symptoms occur.
|
Handheld ECG monitoring using 10-second 6-lead recordings obtained at least twice daily and additionally whenever symptoms occur for 30 days.
Recordings are transmitted through the companion smartphone application to a secure study server.

Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Clinically informative symptom-rhythm correlation with the initially assigned device by 1 month
Zeitfenster: From randomization through the 1-month follow-up visit
|
Proportion of randomized participants with at least one participant-confirmed typical symptomatic episode documented with an interpretable ECG using the initially assigned device by the 1-month follow-up visit and before optional sequential monitoring.
Primary-endpoint success comprises either a positive symptom-rhythm correlation or a negative-only symptom-rhythm correlation.
A positive correlation is a qualifying symptomatic episode with an interpretable ECG showing a rhythm finding judged by central adjudication to be temporally and clinically concordant with that episode.
A negative-only correlation requires at least one qualifying symptomatic episode with an interpretable ECG showing no concordant rhythm finding and no positive correlation by the 1-month visit.

Positive symptom-rhythm correlation
Zeitfenster: By the 1-month follow-up visit
|
Proportion of participants with at least one qualifying participant-confirmed typical symptomatic episode documented with an interpretable ECG showing a rhythm finding judged by central adjudication to be temporally and clinically concordant with that episode.
|
By the 1-month follow-up visit
|
|
Negative-only symptom-rhythm correlation
Zeitfenster: By the 1-month follow-up visit
|
Proportion of participants with at least one qualifying participant-confirmed typical symptomatic episode documented with an interpretable ECG showing no temporally and clinically concordant rhythm finding and with no positive correlation by the 1-month follow-up visit.
|
By the 1-month follow-up visit
|
|
Both positive and negative episodes
Zeitfenster: By the 1-month follow-up visit
|
Proportion of participants with at least one qualifying positive symptom-rhythm correlation and at least one qualifying negative symptom-rhythm correlation.
This measure is descriptive.
|
By the 1-month follow-up visit
|
|
Clinically significant arrhythmia detected during assigned-device monitoring
Zeitfenster: By the 1-month follow-up visit
|
Proportion of participants with at least one centrally adjudicated clinically significant arrhythmia detected during initially assigned-device monitoring, irrespective of symptom association.
Clinically significant arrhythmias are classified using prespecified device-specific operational definitions.
Findings are additionally classified as symptom-associated or not temporally associated with a qualifying typical symptomatic episode.
|
By the 1-month follow-up visit
|
|
Arrhythmia-directed therapeutic intervention
Zeitfenster: Through 3 months after randomization
|
Rate and timing of arrhythmia-directed therapeutic interventions, including medication, catheter ablation, or cardiac device implantation.
|
Through 3 months after randomization
|
|
Overall satisfaction
Zeitfenster: 1-month follow-up visit
|
Overall device satisfaction measured using the prespecified ordinal response scale in the 1-month participant questionnaire.
|
1-month follow-up visit
|
|
EQ-5D-5L
Zeitfenster: Baseline to 1 month
|
Change in the EQ-5D-5L index score from enrollment to the 1-month follow-up visit.
|
Baseline to 1 month
|
|
Healthcare resource utilization and costs
Zeitfenster: Through 3 months after randomization
|
Arrhythmia-related healthcare resource use through 3 months, including additional diagnostic tests, arrhythmia-related medications, emergency department visits, and hospitalizations.
Costs are derived from institutional billing records at participating centers and expressed in Korean won.
The base-case analysis excludes acquisition cost of the study devices because the devices were supplied in kind.
|
Through 3 months after randomization
|
|
Safety Outcome
Zeitfenster: Through 3 months after randomization
|
Number and proportion of participants experiencing device-related or serious adverse events.
Expected device-related events include skin irritation or contact dermatitis associated with the adhesive patch and discomfort associated with device use.
|
Through 3 months after randomization

Sequential-monitoring participant questionnaire
Zeitfenster: 3-month follow-up
|
Among participants who undergo optional sequential monitoring with both study devices, paired ratings of device usability, overall satisfaction, preference, willingness to recommend, and willingness to use each device again are collected using the 3-month head-to-head questionnaire.
This analysis is exploratory because eligibility for sequential monitoring depends on the outcome of the initially assigned strategy
