Apparatus and method for noninvasive measurement of peripheral pressure pulse compliance and systolic time intervals

摘要

Systolic time intervals provide a basis for the determination of total electromechanical systole and offer a physiologic approach to cardiovascular assessment. In addition, examination of the pulse wave contour changes with advancing age and hypertension suggests that these data may be useful in assessing the vascular compliance and peripheral resistance of a subject. Noninvasively obtained peripheral systolic time intervals in normal and pathologic conditions and the automated measurement and continuous plotting of several parameters, including heart rate, pulse wave arrival time, rapid ejection time, peripheral pulse wave contour, and cutaneous pressure pulse are used in assessing the subject.
