Abstract
Pulse transit time (PTT) is used as a noninvasive and cuff-less parameter to estimate blood pressure.In this paper,we develop an algorithm to ohtain PTT rapidly,which is appropriate for micro-processor and could achieve good accuracy in PTT,even in noisy measurements.The algorithm is based on finite impulse response(FIR) filter to reduce the noise and an adaptive threshold to detect the significant points of ECG and PPG.Evaluation of this method is hased on the signals from our PTT-based blood pressure devices It is shown that the method works well for PPT calculation.关键词
