A novel and reliable approach which quantifies the degree of complexity of Late Potential(LP) activity in the: time domain is presented. By defining the LP Attractor in the microvoltage. 3-dimensional space, and then computing the Fractal Dimension (delta) of the Attractor's trajectory, the degree of complexity of LP can be quantified with a single parameter. delta may indicate the chaotic behaviour of the terminal activity of the ventricular depolarisation process. The Fractal Dimension of the LP Attractor in post-h II subjects that are at risk is significantly higher than in post-M1 subjects with low LP activity(p<0.001). delta may be considered as the criterion for discrimination. Fractal Dimension analysis on LP is a novel diagnostic approach aimed at quantifying their complexity in the microvoltage 3-D space, and may be interpreted as a measure of their chaotic behaviour triggering a catastrophic arrhythmic episode.
