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.

摘要

设计了一种基于ARM微处理器s3c2440和Linux系统构建的平台上的心血管功能测试系统，以实现脉搏波采集、特征提取、指标计算等功能。本文主要介绍了硬件电路，并详细描述了触摸屏驱动程序、外部ADC驱动程序以及基于QT的可视化应用程序。该系统使用方便，具有实时性、低功耗的特点。与普通心血管功能测试仪相比，结果表明该系统能够更好地评估心血管功能，特别是在诸如心内膜下心肌活力率和增强指数等几个关键指标上，这些指标显示出良好的相关性。
