Simple linear analysis has not been able to meet current interpretation of the various manifestations of HRV. According to the chaos of HRV, based on the analysis of time domain and frequency domain, so the nonlinear Lorenz plots are added, It contains the linear and nonlinear variation trend of HRV, The nonlinear process and the non periodic motion can be revealed. To enhance the accuracy of the results. Further analysis of various HRV related disorders. For example, a variety of pressure analysis, hypertension, myocardial infarction, etc. Add more valid identification conditions. Although there are still a lot of technical defects and errors. But the research of HRV development in the direction of linear and nonlinear combination, Is a necessary trend. At the present stage, the application of the research based on nonlinear analysis, mostly focused on the data obtained through the ECG method to analyze and research, In this paper, On the basis of reference to Ubioclip, the nonlinear data obtained by the PPG method, and the application in the smart phones and other mobile terminal, Can facilitate the needs of the public, but also can provide a reference for professional medical information.
