As an important part of traditional Chinese medicine (TCM), the pulse taking is the profound essence of TCM. The electrical network model of cardiovascular system coupled with a 10-unit and left-arm simplified model was established using SimPowerSystem components of Matlab based on the previous researches, to analyze the correlation between the pulse wave and human cardiovascular physiological and pathological. By adjusting the hemodynamic parameters of the model, the pulse waveform of different pathological period at the radial artery in hypertensive patients was outputted, thus establishing a certain foundation for objectifying pulse taking and providing with some reference value.
