Inter Class Correlation by Aortic Site. The symbols represent the mean values over all patients+/-95% CI. From the top: Ps – systolic pressure (mmHg), Prmax – maximum reservoir pressure (mmHg), Pxmax – maximum excess pressure (mmHg); Ps – systolic pressure (mmHg), Pn – pressure at the end of systole (mmHg), Pd – diastolic pressure (mmHg); P∞ - asymptotic fall-off pressure (mmHg); ks – systolic rate constant (1/s), kd – diastolic rate constant (1/s).
