In vitro data link pulse rate to Doppler indices; leaves open whether heart rate adjustment is needed in clinical use.
In an in vitro model, Doppler blood-velocity indices are significantly influenced by pulse rate, highlighting the need to account for heart rate in clinical interpretations.
Legarth et al. (1989) studied this question.
