SD1/SD2 ratio may complement linear HRV for resting vagal assessment; leaves open utility during exercise.
Does quantitative two-dimensional vector analysis of a Poincaré plot provide useful information on vagal modulation of heart rate dynamics during exercise compared to linear measures of HRV or ApEn?
Quantitative two-dimensional vector analysis of Poincaré plots provides valuable insights into vagal modulation of heart rate dynamics during exercise that are missed by traditional linear HRV measures.
Tulppo et al. (1996) studied this question.
