Why the study?
Does correction for prevailing heart rate improve heart rate variability repeatability?
Does correction for prevailing heart rate improve heart rate variability repeatability?
Correcting for prevailing heart rate significantly improves the repeatability of heart rate variability measurements.
HR correction may enhance HRV repeatability; leaves open its adoption in clinical or trial settings pending validation.
In stable conditions, HR but not RespRate is the most powerful factor determining HRV reproducibility and even a minimal change of HR may considerably alter HRV. However, the removal of HR impact may significantly improve HRV repeatability. The association between HRV and RespRate seems to be, at least in part, HR dependent.
