Photoplethysmography in the Detection of Atrial Fibrillation
Atrial fibrillation is a common clinical arrhythmia,the incidence of which increases with age,and atrial fibrillation is also a common cause of cardioembolic stroke,so atrial fibrillation detection and early intervention play a crucial role in reducing the healthcare burden on society.However,traditional electrocardiogram testing is time-consuming,labor-intensive,and not suitable for use in large-scale population screening.Wearable devices based on photoplethysmography are non-invasive,convenient,and highly accurate,creating technical conditions for early detection and scientific management of atrial fibrillation,and their feasibility,high sensitivity,and high specificity have been gradually verified.This article will review the epidemiology of atrial fibrillation,photoplethysmography,the application of wearable devices and their limitations for clinical reference.
