Abstract

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.
