Photoplethysmography-based smartwatches for atrial fibrillation detection in stroke survivors: The Liverpool-Huawei Stroke Study
Detecting atrial fibrillation (AF) in stroke survivors is critical for preventing recurrent stroke. However, the diagnostic accuracy of photoplethysmography (PPG)-based smartwatches in this high-risk population remains uncertain. The Liverpool-Huawei Stroke Study evaluated the performance of Huawei smartbands for...
