Nonlinear analysis on 3-channel arterial pulse for fast heart rate algorithm

Nonlinear analysis on arterial pulse is very useful method for finding fast heart rate algorithm and multi-channell waveforms engages faster and more accurate heart rate algorithm. In this paper, we found the relation between the arterial pulse waveform and heart rate through nonlinear analysis with return map. With our own arterial pulse inspector, we collected 3-channel arterial pulse waveforms as continuous signal inputs and analyzed the waveforms using nonlinear characteristic analysis for finding the fast heart rate algorithm. Many types of arterial pulse waveform enables many different analysis results and finally we showed that nonlinear characteristics in the 3-channel arterial pulse waveform can reflect the characteristics of the heart rate sufficiently. As the results of analyses, the nonlinear analysis algorithm showed accurate peak detection and it can easily be used on the heart rate analyzer as a fast heart rate algorithm.
