摘要：This study focuses on the accuracy of arrhythmia detection by intelligent wearable electrocardiogram (ECG) monitoring devices in asymptomatic myocardial ischemia patients during daily activities. It elaborates on the technical principles, features, and working modes of such devices and makes a comparison with traditional ECG monitoring methods. Through a well-designed experimental approach involving data collection and analysis using specific evaluation metrics and standards, the accuracy of arrhythmia detection is evaluated. The relationship between arrhythmia and myocardial ischemia is explored, along with its impact on diagnosis, prognosis, and treatment strategy development. The application of these devices in daily activities, including feasibility, compliance, and analysis during different activity states and long-term trends, is also examined. Despite the potential benefits, technical limitations and barriers to clinical acceptance are identified, and future research directions are proposed. The findings contribute to a better understanding of the role and value of intelligent wearable ECG monitoring devices in the management of asymptomatic myocardial ischemia patients.
