Modelling arterial pulse pressure from heart rate during sympathetic activation

Background: The duration of the time segment between the systolic (SP) and post-dicrotic notch peak pressures (PDP) of the arterial pressure wave in humans has been proposed to be related to arterial pulse pressure (PP).1,2 We considered an effect of RR-interval length on the diastolic pressure run-off and tested the hypothesis that heart rate (HR) affects the timing of systolic and post-dicrotic notch peak pressures.
