Values denote mean ± standard error. SBP, mean arterial pressure (MAP), transit time pulse wave velocity (PWVTT), and distensibility-based pulse wave velocity (PWVdist) as a function of DBP (vertically) and heart rate (HR) (horizontally). Note that values in each row are corrected to a fixed DBP of 60, 85, or 110 mmHg. Hence, as expected, the decreasing pulse pressure with increasing heart rate leads to a decrease in both SBP and MAP with heart rate. HR and DBP dependences are given in units of measurement per 100 bpm or per 100 mmHg, respectively. DBP dependences were calculated at 85 mmHg. All values are corrected for age. P denotes P-value for slope. For DBP dependence, all P < 0.001.
