摘要

维数是非线性动力学中的一个基本概念。盒数尺寸(BCD)是确定尺寸的一种可用方法。我们研究了25例心肌梗死(MI)后患者的二维和三维庞加莱图的心率信号维度以及年龄和性别匹配的对照组。根据2D首次回归图,正常受试者的平均BCD为1.46/spl plusmn/0.09,而梗死组的BCD明显较低:1.34/spl plusmn/0.17 (p=0.003)。从分析中排除异位数据会导致结果维度发生很大变化。

The dimension of 2D and 3D Poincare plots obtained from 24 hour ECG registrations
The dimension is a basic concept in non linear dynamics. The box counting dimension (BCD) is one of the methods that is available to determine the dimension. We studied the dimension of the heartrate signal in both 2 and 3D Poincare plots in a group of twenty five post myocardial infarction (MI) patients together with an age and sex matched control group. The average BCD from the normal subjects based on a 2D first return plot was 1.46/spl plusmn/0.09, while in the infarction group this was significantly lower: 1.34/spl plusmn/0.17 (p=0.003). Excluding ectopic data from the analysis caused large changes in the resulting dimension.
