Abstract：
Heart rate variability (HRV) is an early marker of risk for various health conditions, and its analysis serves as a valuable tool for assessing older adults. This study aimed to describe the reference values of HRV parameters in older adults through a systematic review of the literature. The review included searches in MEDLINE (via PubMed®), EMBASE, Latin American and Caribbean Health Literature, Scopus, and Web of Science (WOS). Studies presenting reference values for at least one HRV linear analysis measure in older adults were considered eligible. Out of 1618 studies identified, only 11 met the inclusion criteria. Sample sizes of older adults ranged from 21 to 6250 subjects. The HRV measures assessed (mean RR intervals, SDNN, RMSSD, PNN50, LF, HF, and LF/HF ratio) varied significantly between studies, with no standardized methods for HRV analysis. We concluded that reference values for HRV measures in older adults vary widely between studies. The scientific literature on HRV reference values in older adults is still limited, and future studies should standardize assessment methods for HRV measures in this population.
摘要：
心率变异性（HRV）是各种健康状况风险的早期标志，它的分析是评估老年人的一个有价值的工具。本研究旨在通过对文献的系统回顾，描述老年人HRV参数的参考值。该评论包括MEDLINE中的搜索（通过PubMed®），EMBASE,拉丁美洲和加勒比健康文献，Scopus,WebofScience(WOS)在老年人中呈现至少一种HRV线性分析量度的参考值的研究被认为是合格的。在1618项研究中，只有11人符合纳入标准。老年人的样本量为21至6250名受试者。评估的HRV测量值(平均RR间期，SDNN,RMSSD,PNN50,LF,HF,和LF/HF比率)在研究之间差异显著，没有HRV分析的标准化方法。我们得出的结论是，老年人HRV测量的参考值在研究之间差异很大。关于老年人HRV参考值的科学文献仍然有限，未来的研究应规范该人群HRV测量的评估方法。
