光学体积描记术用于心房颤动检测的研究进展

Photoplethysmography in the Detection of Atrial Fibrillation

心房颤动(房颤)是临床常见的心律失常,发病率随着年龄增长而增加,同时房颤也是心源性脑卒中的常见原因,所以进行房颤检测并早期干预,对减轻社会医疗负担起着至关重要的作用。但传统的心电图检测耗时、耗力,并不适合在大规模人群中筛查。基于光学体积描记术的可穿戴设备具有无创、便捷、准确性高等特点,为早期发现和科学管理房颤创造了技术条件,其可行性、高灵敏度和高特异度正逐步得到验证,现从房颤的流行病学、光学体积描记术、可穿戴设备应用现状及局限性等方面进行综述,供临床参考。

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.
