Inconsistent relation of nonlinear heart rate variability indices to increasing vagal tone in healthy humans.

CONCLUSIONS: These data suggest an inconsistent relationship between responses of nonlinear HRV indices and RR interval to changes in cardiac vagal tone. Therefore, nonlinear HRV indices may not be reliable indices of cardiac vagal control in healthy humans.
