Why the study?
Are five-minute recordings of heart rate variability in non-laboratory settings repeatable and informative for population studies?

Answers are grounded in this paper and cite their sources.
Five-minute HRV recordings in non-laboratory settings are stable over time and can be reliably used as an informative metric in population-based studies.
Short recordings of HRV in a non-laboratory setting are stable over months and therefore characteristic of an individual. Strong age and sex effects were evident. HRV derived from short recordings can be informative in population based studies.
