洛伦兹散点图及其在房颤自动诊断中的应用

Lorenz Plot and Its Application in Automatic Diagnoses of Atrial Fibrillation ECG Signals

介绍了洛伦兹散点图的概念,以及在使用散点图时的定性分析和定量指标,并给出了长短轴比值的参数。利用散点图对比了房颤和窦性心率心电图,指出了在不同情况下散点图形状的区别,以及长短轴比值的差异。在进行心电信号的自动检测时,洛伦兹散点图可以作为辅助判断房颤的标准。

In this paper is presented the Lorenz plot, the qualitative analyses and quantitative parameters of the plot. The long axis vs short axis （LVS） parameter is given. Atrial Fibrillation Electrocardiogram（AF ECG） is compared with sinus ECG by use of Lorenz plot. Then the difference in their plots and the parameter of LVS is pointed out. Lorenz plot finding is useful for the AF disease in automatic diagnoses of ECG signals.
