    摘要: A novel method for estimating the end-systolic pressure-volume relationship (ESPVR) is presented. The method provides for accurate estimation of the ESPVR from a single beat of the cardiac cycle. The method is based on normalized human time varying elastance curves [E.sub.N (t.sub.N)]. The ESPVR is estimated from one beat using PV data measured at normalized time t.sub.N and end-systole (t.sub.max) to predict intercept: ##EQU1## and slope: E.sub.max(SB) =P(t.sub.max)/[V(t.sub.max)-V.sub.0(SB) ]. The present invention provides a method for ESPVR estimation which is non-invasive and particularly applicable for bedside applications.

    摘要: A method for detecting vascular sclerosis is revealed. Firstly set a cuff on a human hand. Then inflate the cuff and later deflate the cuff. Next measure a pressure of the cuff and generate a pressure sensing signal. Process the pressure sensing signal to generate a processed signal and convert the processed signal. Then calculate a systolic pressure and a diastolic pressure according to the converted processed signal and also obtain a vasodilation constant. Thus a hardening of blood vessels is detected according to the vasodilation constant.
