基于统计深度函数法的心电图P波振幅多元参考值范围

Establishment of multivariate reference range of P-wave amplitude based on depth function

目的本研究试图从多指标关联性出发,建立心电图指标的多元参考值范围。方法采用统计深度函数MHD法,以某校777名女大学生为样本,以心电图P波振幅为例建立心电图指标的多元参考值范围。结果通过计算得到其P波振幅12导联95%的参考值范围为统计深度Depth≥0.0355216。结论本文所得的心电图指标的多元参考值范围,将丰富的心电图数据加以综合利用,可为心电图临床诊断提供参考依据。

Objective To establish a multivariate reference range for ECG while considering the relation between multiple variables.Methods A total of 777 female undergraduates in a university were taken as the subjects and the P-wave amplitude was taken as an example to establish a multivariate reference range for P-wave amplitude by using Mahalanobis Depth Function.Results P-wave amplitude of the female undergraduates was established as follows：for a 95% CI of multivariate reference range,Depth≥0.035 521 6.Conclusion Multivariate reference range for ECG obtained in this study allows for a comprehensive utilization of the ECG data and can help the clinical diagnosis using ECG.
