目的探究动态心电图自动分析功能准确性测试方法。方法通过分析YY 9706.247-2021标准对心电图自动分析功能准确性测试的标准数据库和试验要求,在Cygwin环境下构建WFDB软件包,利用bxb、rxr、mxm和epicmp等WFDB应用程序将标准数据库提供的参考注释文件与动态心电图自动分析算法生成的测试注释文件进行比较,并统计输出数据。结果采用本文论述的方法,对心电工作站软件进行测试,形成了QRS检测、室性异位搏动、室上性异位搏动、成对室性异位搏动、短段室性异位搏动、长段室性异位搏动、心房颤动片段敏感度和阳性预测值的统计报告。结论本文方法有助于动态心电图系统的研发和加深检测人员对标准条款的理解,提高动态心电图自动分析功能准确性的检测效率,进而促进该类产品在主动健康和老龄化科技应对中发挥巨大的作用。

Objective To explore the testing method for the accuracy of dynamic electrocardiogram(ECG)automatic analysis function.Methods By analyzing the standard database and test requirements of the YY 9706.247-2021 standard for the accuracy test of ECG automatic analysis function,the WFDB software package was constructed under the Cygwin environment.The WFDB applications programs such as bxb,rxr,mxm and epicmp were used to compare the reference note files provided by the standard database with the test note files generated by the dynamic ECG automatic analysis algorithm,and the output data were counted.Results The ECG workstation software was tested by using the method described in this paper,and the statistical reports of QRS test,ventricular ectopic beat(VEB),supra-VEB,paired VEB,short segment VEB,long segment VEB,and episode sensitivity and positive predictive value of atrial fibrillation were formed.Conclusion This method can be helpful for the research and development of Holter system,deepen the understanding of the standard terms for the testing personnel,improve the detection efficiency,and further promote these products to play a huge role in active health and aging technology response.
