RODRIGUEZ, Javier et al. Fractal geometric generalization of normal left ventriculographies and with mild dysfunction. Acta Med Colomb [online]. 2014, vol.39, n.2, pp.131-136. ISSN 0120-2448.

Introduction: Cardiac structure is irregular by nature; its proper characterization is done by application of fractal geometry. From this geometry an objective diagnosis of left ventriculogram was developed. Objective: to develop a theoretical generalization of left ventricular dynamics in states of normality and mild disease, from the objective and reproducible previously developed mathematical diagnosis. All possible ventricular structures were calculated during cardiac dynamics from the degrees of similarity for cases that evolve between normal and mild in search of mathematical prototypes of normality and mild disease. Results: It was established that all of the possible prototypes for normal ventricular structure and mild disease are 1345; 551 correspond to normality and 794 to mild disease. Comparing the degree of similarity of previously measured ventricles, with the obtained prototypes, it was found that its measures were included in the generalization. Conclusion: a new methodology for clinical application reproducible and of objective diagnostic aid independently of clinical classifications, based on the geometric generalization of ventricular dynamics, was developed.
