| dc.description | La dinámica cardíaca caracterizada en el contexto de la teoría de sistemas dinámicos permite diferenciar y predecir estados cardíacos normales, diferentes niveles de enfermedad, así como la evolución hacia la enfermedad. El propósito de este estudio es aplicar una metodología desarrollada previamente a 450 registros electrocardiográficos para establecer su efectividad y compararla con el diagnóstico clínico convencional. La metodología se aplicó a 50 Holters normales y 400 Holters con diferentes patologías. Luego de enmascarar las conclusiones diagnósticas, se utilizó la frecuencia cardíaca mínima y máxima y el número total de latidos cada hora para construir un atractor para cada Holter en un espacio de fase, mediante el cual se evaluó la probabilidad, entropía y sus proporciones en pares ordenados. de frecuencia cardíaca. Se compararon las medidas con los parámetros físicos y matemáticos de normalidad y enfermedad previamente establecidos. Se desenmascararon las conclusiones diagnósticas y las fechas de la historia clínica de cada Holter, para calcular la sensibilidad, especificidad y coeficiente Kappa respecto al Gold-standard. Esta metodología permitió diferenciar matemáticamente la dinámica de la enfermedad normal, aguda y crónica y la evolución entre estos estados. Se obtuvo una sensibilidad y especificidad del 100% y el coeficiente Kappa fue igual a 1, demostrando su utilidad diagnóstica. | spa |
| dc.description.abstract | Heart dynamic characterized within the context of dynamical systems theory allows differentiating and predicting normal cardiac states, different levels of disease, as well as evolution towards disease. The purpose of this study is to apply a previously developed methodology to 450 electrocardiographic registers to establish its effectiveness and comparing it with clinical conventional diagnosis. The methodology was applied to 50 normal Holters and 400 Holters with different pathologies. After masking the diagnostic conclusions, the minimum and maximum heart rate and the total number of beats each hour were used to construct an attractor for each Holter in a phase space, by means of which the probability, entropy and their proportions were evaluated in ordered pairs of heart rate. Measures were compared with the physical and mathematical parameters of normality and disease previously settled down. Diagnostic conclusions and dates from medical history of each Holter were unmasked, to calculate sensibility, specificity and coefficient Kappa respect to Gold-standard. This methodology allowed mathematically differentiating the normal, acute and chronic disease dynamics and the evolution among these states. Sensibility and specificity of 100% were obtained and Kappa coefficient was equal to 1, demonstrating its diagnostic utility. | spa |
