Summary

We hypothesize that an AI-guided AF risk stratification approach, particularly when combined with intensified rhythm monitoring using wearable devices and extended ECG patches, will significantly increase AF detection rates compared with standard care. By enabling earlier identification of patients who may benefit from anticoagulation therapy, this strategy has the potential to improve clinical outcomes while minimizing unnecessary exposure to anticoagulant-related bleeding risks. Ultimately, this trial seeks to provide robust clinical evidence supporting the integration of AI-assisted ECG analysis into routine post-stroke care, advancing precision medicine and optimizing resource allocation for patients with ischemic stroke.

Conditions

Interventions

DEVICE

Active Follow-up Group

High-frequency electrocardiogram (ECG) monitoring was conducted, using a smartwatch with continuous photoplethysmography (PPG) monitoring, supplemented by an external single-lead ECG patch for 14 days. Participants recorded ECGs for 14 days immediately after discharge. If the smartwatch detected atrial fibrillation, the patch would be automatically applied for 14 days of recording. After recording, the patch was mailed or delivered in person to the research team for analysis.

OTHER

Standard Follow-up Group

followed a standardized follow-up procedure by a neurologist. Each follow-up visit included a medical history and physical examination, without further cardiac-related monitoring. However, if the patient presented with symptoms of arrhythmia, the physician could consult a cardiologist or perform a preliminary 12-lead ECG.
