Key result
Reference values for heart rate variability measures in older adults vary widely across 11 studies, highlighting a lack of standardized assessment methods.
Why the study?
Heart rate variability is an early risk marker and useful assessment tool in older adults, but reference values needed to be described.
What are the reference values for heart rate variability parameters in older adults?
Systematic Review
What are the reference values for heart rate variability parameters in older adults?
There is a wide variation in reported reference values for heart rate variability in older adults, highlighting the need for standardized assessment methods.
Provides standardized HRV reference values for older adults; extends risk stratification tools and guides future autonomic research.
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.

Rocha et al. (2024) conducted a systematic review in Older adults. Heart rate variability (HRV) assessment was evaluated on Reference values of HRV parameters. Reference values for heart rate variability measures in older adults vary widely across 11 studies, highlighting a lack of standardized assessment methods.
