| Abstract: | Because of the simpleness, high efficiency, flexibility and other advantages of virtual instrument technology, to design a pulse signal processing and analysis via LabVIEW programming, it was based-on the hardware of self-development pulse diagnosing system. Processing and analysis of the pulse signal such as cycle recognition, the elimination of baseline drift, extraction of feature parameters and calculation of cardiovascular status parameter were implemented successfully. Experiments show that the system is stable and the desired results of pulse signal analysis and processing are obtained. |
| Keywords: | pulse signal feature parameters LabVIEW |
