摘要：
A simple non-invasive system for the measurement of PPGsignal sufficient for estimating multiple vascular parameters such as, Pulse Wave Velocity (PWV), Stiffness Index (51), Reflection Magnitude (RM) and pulse duration by a two-pulse synthesis (TPS) based system. The system and method favor analysis of multiple parameters related to a measured digital volume pulse (DVP). The system performs Photoplethysmograph (PPG) signal analysis by involving two mathematically well-defined Rayleigh and/or modified Rayleigh-type pulses for waveform synthesis leading to close approximation of a measured PPG signal. The reconstructed pulse resembles the original measured pulse very closely with low Mean Square Error (MSE). The system measures clinically relevant parameters such as, "Reflection Magnitude" (RM), "delay between first and second peaks (.M)", height of reflected pulse (P2) and also clinically insightful parameters such as Differential Pulse Spread (DPS), Spread-Delay Ratio (SDR) and the like. The standard time tested parameters such as, average heart rate, pulse duration, PWV etc. are also measured by the system. The TPS based system is suitable for mass screening of population against card iovascular diseases.
