Design
Other, Randomized order for breathing conditions
Follow-up
2 separate days

Supports preferring time- and nonlinear HRV parameters; frequency-domain reliability needs controlled breathing, leaving standardization open.
Does breathing type and artifact correction level affect the intersession reliability of heart rate variability parameters?
HRV monitoring is most reliable when using time-domain and nonlinear parameters with 'low' artifact removal, and controlling breathing rate improves the reliability of frequency indices.
