Atrial Fibrillation Detection Using MEMO Patch in Patients With Stroke of Unknown Cause

Condition(s) studied

Investigational drug(s) / intervention(s)

MEMO Patch M and MEMO Patch2: During hospitalization, participants will wear MEMO Patch M, a single-lead wearable ECG patch, for 12 hours to up to 8 days. A 24-hour Holter monitor will also be performed during hospitalization. Before discharge, investigators will review the MEMO Patch M and Holter results to assess the need for implantable loop recorder (ILR) implantation. At the time of discharge, participants will wear MEMO Patch2 for up to 14 days for the first ECG monitoring period. One month after discharge, participants will undergo the second ECG monitoring period with MEMO Patch2 for up to 14 days.

Study summary

The purpose of this study is to evaluate the efficacy and safety of a wearable device in detecting previously undiagnosed atrial fibrillation through non-invasive long-term monitoring using a wearable single-lead ECG patch (MEMO Patch M, MEMO Patch2) in 100 patients with Embolic Stroke of Undetermined Source (ESUS) who require atrial fibrillation screening. Participants who meet all inclusion and exclusion criteria and provide written informed consent will wear the MEMO Patch M and undergo in-hospital telemetry monitoring using MEMO Cue for a minimum of 12 hours and up to 8 days. During hospitalization, 24-hour Holter monitoring will also be conducted. Before discharge, the investigator will review these results to determine whether implantable loop recorder (ILR) implantation is necessary. At the time of discharge, participants will wear MEMO Patch2 for up to 14 days for the first ECG monitoring period. One month after discharge, the investigator will review the results of the first monitoring and initiate the second ECG monitoring with MEMO Patch2. Three months after discharge, the results of the second ECG monitoring will be reviewed, and participation in the clinical trial will be completed.

Eligibility

Primary outcome measure(s)

• Detection rate of Atrial Fibrillation (%) — During V1 (Day 0 to Day 8)
  The detection rate of atrial fibrillation (AF) will be evaluated based on MEMO Patch M during telemetry monitoring and 24-hour Holter monitoring. The AF detection rate by MEMO Patch M will be calculated as the number and percentage of participants in whom AF is detected at least once either through alarms or analysis results. The AF detection rate by 24-hour Holter will be calculated as the number and percentage of participants in whom AF is detected at least once during Holter analysis. The final determination of atrial fibrillation will be made according to the investigator's interpretation.
