心肌动作电位的定量分析是医学科研与实验中一项重要的工作。传统的测量方法是采用示波器显示和照像记录测量法,这种测量方法不仅速度慢,而且难以做到精确。近十几年来,微处理机技术发展很快,许多医学仪器都采用了微处理机技术,把信号采集和处理一体化,这不仅使信号处理自动化,而且还大大地提高了检测速度和检测精度。我们设计了一个微机化的测量系统。本系统采用总线结构,灵活方便,成本低,既可测量心肌动作电位,又可以做为记忆示波器使用。本系统具有并行打印机接口和数字磁带
Quantitative analysis of myocardial action potential is an important task in medical research and experiment. The traditional method of measurement is the use of oscilloscope display and photographic recording measurement method, this measurement method is not only slow, but difficult to be precise. In recent decades, microprocessor technology has developed rapidly, many medical instruments are used microprocessor technology, the signal acquisition and processing integration, which not only automates signal processing, but also greatly improve the detection speed and detection accuracy . We designed a computerized measurement system. The system uses a bus structure, flexible and convenient, low cost, can measure the myocardial action potential, but also can be used as a memory oscilloscope. The system has a parallel printer interface and digital tape
