Theoretical geometric generalization of left ventriculogram during cardiac dynamic of clinical application
Abstract: Fractal geometry has proven to be adequate for mathematical description of irregular objects such as the human body. Based on this geometry, an objective and reproducible representation of a left ventricle was previously developed. The aim of this research was to develop a simulation based on this methodology that allows establishing all possible left ventricular dynamics from normality to severe disease. All possible combinations for each state were determined from maximum and minimum values of similarity degrees previously found for normal ventricular structures with mild, moderate and severe disease. The whole spectrum of ventricular dynamics between normality and disease during cardiac dynamic was quantified. There were found out 2,165 possible prototypes of ventricular structure: 551 of healthy states, 794 of mild and moderate disease, and 820 of severe disease. It was found that the similarity degrees of ventricle measures observed in previous studies were included within the identified prototypes. Thus, a generalization that establishes all possible ventricular fractal prototypes that may be found in clinical practice was developed, which is able to differentiate a normal state from several degrees of disease.
