背景：越来越多的可穿戴设备声称能够提供准确、廉价且易于应用的心率变异性 (HRV) 指数。这主要是通过使用可穿戴光电体积描记法 (PPG) 和/或心电图 (ECG) 通过简单且非侵入性的技术来实现，以替代通过心电图估计 RR 间期的金标准。尽管文献中已经评估了脉率变异性 (PRV) 和 HRV 之间的一致性，但所报告的结果仍然没有结论，尤其是在使用可穿戴设备时。目的：本系统综述的目的是调查可穿戴设备是否能够可靠且精确地测量休息时和运动期间的经典 HRV 参数。材料和方法：实施搜索策略，从 MEDLINE 和 SCOPUS 数据库以及互联网搜索中检索相关文章。根据预定的纳入/排除标准对检索到的 308 篇文章进行进一步评估。结果：纳入 18 项研究。其中16个集成了ECG-HRV技术，其中2个集成了PPG-PRV技术。所有研究人员都检查了可穿戴设备在休息时检测 RV 的准确性，而只有 8 个研究人员在运动期间进行了检测。经典心电图得出的 HRV 与可穿戴 RV 之间的相关性在休息期间从非常好到极好，但随着运动水平的增加而逐渐下降。结论：可穿戴设备可能为测量 RV 提供有前途的替代解决方案。然而，就涉及的受试者数量、隐含的采集和分析技术而言，需要使用适当的方法在非平稳条件下进行更稳健的研究。
BACKGROUND: A growing number of wearable devices claim to provide accurate, cheap and easily applicable heart rate variability (HRV) indices. This is mainly accomplished by using wearable photoplethysmography (PPG) and/or electrocardiography (ECG), through simple and non-invasive techniques, as a substitute of the gold standard RR interval estimation through electrocardiogram. Although the agreement between pulse rate variability (PRV) and HRV has been evaluated in the literature, the reported results are still inconclusive especially when using wearable devices.AIM: The purpose of this systematic review is to investigate if wearable devices provide a reliable and precise measurement of classic HRV parameters in rest as well as during exercise.MATERIALS AND METHODS: A search strategy was implemented to retrieve relevant articles from MEDLINE and SCOPUS databases, as well as, through internet search. The 308 articles retrieved were reviewed for further evaluation according to the predetermined inclusion/exclusion criteria.RESULTS: Eighteen studies were included. Sixteen of them integrated ECG - HRV technology and two of them PPG - PRV technology. All of them examined wearable devices accuracy in RV detection during rest, while only eight of them during exercise. The correlation between classic ECG derived HRV and the wearable RV ranged from very good to excellent during rest, yet it declined progressively as exercise level increased.CONCLUSIONS: Wearable devices may provide a promising alternative solution for measuring RV. However, more robust studies in non-stationary conditions are needed using appropriate methodology in terms of number of subjects involved, acquisition and analysis techniques implied.
