Abstract

Two cardiovascular parameters of emerging interest suitable for estimation of non-invasive, beat-to-beat, and without cuff, blood pressure parameters are pulse width (PW) and pulse transit time (PTT). In this study the performance of both parameters in estimating beat-to-beat systolic blood pressure (SBP) and diastolic blood pressure (DBP) is analyzed. The overall data set used in the study includes synchronous electrocardiogram signal (ECG), pulse photoplethysmography signal (PPG) and continuous blood pressure signal of 16 healthy subjects during tilt table test, which provokes significant changes in SBP and DBP due to postural changes.
