摘要：

為尋求一種精確的脈搏波特征提取方法，提取更多的脈搏波形特征，揭示心電脈搏在時(shí)域上的相關(guān)性，使用MP425數(shù)據(jù)采集卡和LabVIEW構(gòu)成的數(shù)據(jù)采集系統(tǒng)同步采集ECG信號(hào)和脈搏波信號(hào)，對(duì)ECG信號(hào)和脈搏波信號(hào)進(jìn)行分析和處理，采用能量算子法檢測(cè)心電信號(hào)R波；基于同步采集的ECG和脈搏波信號(hào)，提出一種應(yīng)用ECG信號(hào)的R波和T波來(lái)提取Pulse wave的重搏波和峰值的方法。經(jīng)過(guò)分析與實(shí)驗(yàn)驗(yàn)證，該方法能準(zhǔn)確找到脈搏波波峰和重搏波位置，并具有較強(qiáng)的抗干擾能力，為研究心電脈搏之間的關(guān)系提供了一種新的方法。

In order to explore an accurate method of pulse waveform feature extracting，detect more pulse waveform features and reveal the correlation between electrocardiogram (ECG) and pulse in the time domain，ECG signals and pulse wave signals were collected from the subjects by using the MP425 card and LabVIEW acquisition system. The ECG signals and the pulse wave signals were analyzed and processed. The R-wave of ECG was detected by using the method of teager energy operator(TEO). Based on synchronized ECG and pulse wave signals, a method was proposed for detecting the characteristic points of pulse wave by R-wave and T-wave of ECG. After analysis and experimental verification, it was proved that the positions of pulse peek and dicrotic wave in pulse waveform were exactly determined by proposed method, that had strong interference-free ability, and provided a new approach for exploring the relation between ECG and pulse wave.
