Diagnostic Validation of Wearable ECG Monitoring Patch, ATP-C120

The prevention of stroke associated with atrial fibrillation is a leading global health concern. This devastating event is largely preventable with anticoagulant therapy. Therefore, the early detection and accurate diagnosis of arrhythmia are crucial for prevention of adverse outcome. However, because atrial fibrillation is often intermittent and mostly asymptomatic, it is difficult to capture an excise event. Conventional electrocardiogram (ECG) monitoring devices including multi-lead portable ECG monitoring device, event-detection monitoring device, and implantable ECG monitoring device are useful for early detection of atrial fibrillation, but these devices have various drawbacks such as requirement of multiple out-patient visits and need of invasive implantation of devices. A new wearable patch-type device, ATP-C120 (ATsens, Seongnam, Korea) is a novel, single-lead ECG monitoring device and can continuously monitor the ECG signal for upto 11 days. It has recently demonstrated its diagnostic capability and safety compared to the conventional ECG monitoring systems . Yet, it has not widely used in real-world. So, this study is designed to experiment its diagnostic capability of new-onset atrial fibrillation in high risk patients. Several studies reported that validated CHA2DS2-VASc score has high performance in predicting new-onset atrial fibrillation and there are over 10 percent of new-onset atrial fibrillation in patients whose calculated CHA2DS2-VASc scores are ≥ 2. Thus, through this study, the investigators sought to evaluate the validation of early detection of new-onset atrial fibrillation by ATP-C120.
