Diagnostic Value of a Wearable Continuous Electrocardiogram Monitoring Device (AT-Patch) for New-Onset Atrial Fibrillation in High-Risk Patients: Prospective Cohort Study

Diagnostic Value of a Wearable Continuous Electrocardiogram Monitoring Device (AT-Patch) for New-Onset Atrial Fibrillation in High-Risk Patients: Prospective Cohort Study

It was determined that atrial fibrillation occurred in 4.4% (14/320) and 3.8% (12/320) of patients by cardiologist 1 (C1) and cardiologist 2 (C2), respectively, with example recordings of a detected episode shown in Figure 1. It is evident that this episode of atrial fibrillation began following a premature beat (Figure 1 A) and thereafter presented as irregular heartbeats in the absence of P waves (Figure 1 B).

Accuracy of Artificial Intelligence–Based Automated Quantitative Coronary Angiography Compared to Intravascular Ultrasound: Retrospective Cohort Study

Accuracy of Artificial Intelligence–Based Automated Quantitative Coronary Angiography Compared to Intravascular Ultrasound: Retrospective Cohort Study

In this study, we validated the performance of AI-based QCA (AI-QCA) compared with IVUS in patients with coronary artery disease. This was a retrospective analysis of patients with coronary artery disease who underwent coronary intervention at a single tertiary center. Fifty patients who underwent IVUS-guided percutaneous coronary intervention (PCI) in Uijeongbu Eulji University Hospital between October 2021 and July 2022 were included.

Surveillance of Arrhythmia in Patients After Myocardial Infarction Using Wearable Electrocardiogram Patch Devices: Prospective Cohort Study

Surveillance of Arrhythmia in Patients After Myocardial Infarction Using Wearable Electrocardiogram Patch Devices: Prospective Cohort Study

A wearable ECG monitoring patch device can detect ECG rhythm disturbances in patients with postmyocardial infarction. In this study, we investigated the incidence of arrhythmias in patients with postmyocardial infarction using another new wearable patch-type device—AT-Patch (ATP-C120; ATsens). This study is a nonrandomized, single-center, prospective cohort study. We evaluated patients who had been admitted to our hospital for myocardial infarction and discharged after treatment.
