    • Abstract:
      A cardiovascular function testing system was designed in platform which was built with ARM microprocessor s3c2440 and Linux system, to achieve pulse wave acquisition, feature extraction, index calculation and so on. This article mainly describes the hardware circuit, and describes the touchscreen driver, external ADC driver, and visualization QT-based applications in detail. The system is easy to use, with real-time, low power consumption. Compared with common cardiovascular function test instrument, the results shows that the system can better assess the cardiovascular function, expecially in several key indicators like subendocardial myocardial viability rate and augmentation index, the indicators show good correlations.
