摘要

心肌梗死(MI)后心室晚期电位(VLP)的检测是一个有用的危险指标。提出了一种可靠的基于分形维数分析的VLP异常检测新方法。计算在微电压三维空间追踪的VLP“吸引子”的分形维数(δ)，为检测心肌梗死后患者VLP异常活动提供了可靠的参数。一项临床研究表明，δ > 1.30可作为危险标准。

A fractal approach to the problem of ventricular late potential detection

Detection of ventricular late potentials (VLP) following myocardial infarction (MI) can be a useful risk indicator. A reliable novel approach for detecting abnormal VLP activity based on fractal dimension analysis is presented. Computation of the fractal dimension (δ) of the VLP "attractor" traced in the microvoltage, 3-dimensional space, provided a reliable parameter for detecting abnormal VLP activity in post-MI patients. A clinical study suggested that a value of δ > 1.30 can be a risk criterion.
