简要总结
This exploratory medical device study evaluated the arrhythmia diagnostic yield of MEMO Patch V2, a wearable patch-type electrocardiographic monitor, in adults with suspected arrhythmia who presented with symptoms such as palpitations or dizziness, or who had cryptogenic ischemic stroke or transient ischemic attack. The diagnostic yield of MEMO Patch V2 was compared with that of conventional 24-hour ambulatory electrocardiography (Holter monitoring). The study also assessed ECG signal quality, participant compliance, usability and satisfaction, and skin-related adverse events. The findings were intended to provide preliminary data for planning a future large-scale clinical study.
详细描述
This was a multicenter, non-randomized, controlled, open-label pilot clinical trial conducted at Korea University Anam Hospital and Seoul National University Bundang Hospital. Adults aged 19 to 80 years who required ECG monitoring because of suspected arrhythmia associated with palpitations or dizziness, or because of cryptogenic ischemic stroke or transient ischemic attack, were eligible. All participants underwent simultaneous application of a conventional 24-hour Holter monitor and MEMO Patch V2 on Day 0. The Holter monitor was removed and returned on Day 1, while MEMO Patch V2 continuously recorded a single-channel ECG for up to 14 days and was returned by courier. Participants attended an end-of-study visit on Day 21 ± 3 days. Effectiveness was evaluated by comparing arrhythmia detection rates and by assessing ECG signal quality, participant compliance, and device usability and satisfaction. Safety was evaluated based on skin-related adverse events occurring at the application site. A total of 150 participants were enrolled; the Full Analysis Set included 147 participants, the Per-Protocol Set included 141 participants, and the Safety Set included 150 participants.

结局指标
主要结局
Arrhythmia Detection Rate (%)
时间窗: From device application on Day 0 through completion of MEMO Patch V2 monitoring, up to 14 days
The proportion of participants diagnosed with at least one arrhythmia using MEMO Patch V2 was compared with the proportion diagnosed using the 24-hour Holter monitor. Arrhythmias included premature atrial contraction, premature ventricular contraction, atrial tachycardia, atrial flutter, atrial fibrillation, paroxysmal supraventricular tachycardia, ventricular tachycardia, second- or third-degree atrioventricular block, sinus pause, and other arrhythmias. Comparisons included the total monitoring periods (Holter: 24 hours; MEMO Patch V2: at least 7 days) and the first 24 hours for both devices.
次要结局
- ECG Signal Quality(Up to 14 days)
- Participant Compliance(Up to 14 days)
- Usability and Satisfaction(Day 21 ± 3 days)
