摘　　要：数字心电图机是临床使用最广泛的、心脏疾病相关的检测设备。现行使用的数字心电图机检定规程,通过给心电图机一个已知信号,测量其描记的信号幅值,与已知信号对比,从而确定心电图机波形识别能力是否合格。检定过程中,测量所描记心电信号的幅值时,由于测量精度高且数据繁杂,通常要花费检定员很长时间。本文主要研究通过LabView的图像处理技术,对心电图机描记的波形幅值实现更方便、更快速、更准确的测量和计算。Digital electrocardiograph is the most widely used divice for heart disease in hospitals. As we know from the verification regulation for digital electrocardiograph,compare the amplitude of the standard signals and the processed signals,and determining if the digital electrocardiograph is up to the standard. In the process of verification,because of the high precision and multifarious data,the verification would take a long time to finish. The thesis is focused on how to faster and more accurate for measuring the amplitude of the electrocardiograph by the LabView Vision.
