Lorenz 散点图中45°线远端形成“曲尺”状图形4例分析
Square-shaped figure at the distal end of 45°line in Lorenz scatterplot:analysis on four cases
摘要
Abstract
To investigate the forming principal of square-shaped figure at the distal end of 45° line in Lorenz scatterplot and the application of reverse analysis technology in analyzing this kind of figures,this paper analyzes 4 cases whose characteristic manifestation of Lorenz scatterplot matched up with the square-shaped figures produced by escape beat or VVI pacing.By derivation based on mapping principle of scatterplot and reverse analysis,it was found that the square-shaped figure can produce uniquely representative changes according to different dominant rhythm,escape interval, and frequency before and after escape beat.With the reverse analysis technology of ECG scatterplot, the efficiency and accuracy in analyzing and diagnosing such cases can be elevated quickly.关键词
