In this paper, blood pressure was estimated using the time difference between the R peak of Electrocardiography and the peak of Photoplethysmogram. The feature point detection algorithm is improved, the R-wave of ECG is detected by the adaptive threshold method, and the peak of PPG is detected by relative position, which greatly improves the efficiency of the improved algorithm and the accuracy of PTT(Pulse Transit Time) detection. And on this basis, the vascular elasticity variable is added. Through the correlation analysis of the data, the strong correlation between PTT and systolic blood pressure(SBP) can be obtained, and there is a moderate correlation between PTT and diastolic blood pressure(DBP).
