Impact of heart rate on reproducibility of heart rate variability analysis in the supine and standing positions in healthy men

摘要

OBJECTIVE:The reliability of heart rate variability (HRV) analysis is not yet fully understood, especially considering different body positions and the mathematical influence of heart rate. The aim of this study was to evaluate the reliability of HRV in supine and standing positions, with and without mathematical adjustment of HRV by the average R-R interval (iRR).
