Introduction: an exponential law has been found for chaotic dynamic cardiac systems, making it possible to quantify the differences between normal and pathological cardiac dynamics. Methodology: 120 electrocardiographic records were analyzed, 40 corresponded to subjects within the limits of normality and 80 with different pathologies. For each holter the attractors generated with the data during 18 hours and throughout the dynamics were analyzed. The fractal dimension of the attractor and its spatial occupation were calculated. To these measures was applied the diagnosis mathematical evaluation previously developed, comparing the evaluation for 18 hours and for the whole registry; sensitivity, specificity and Kappa coefficient were finally calculated. Results: For the normal dynamics, the occupancy spaces in the Kp grid were between 200 and 381 for the evaluation of the whole holter, and between 201 and 384 in the evaluation during 18 hours, showing the closeness in the measurements, which allows that the decrease in the time of the evaluation is consistent, this same proximity was observed for the diseased and acute dynamics. Conclusion: It was evidenced the clinical applicability in 18 hours of the exponential law in the chaotic cardiac dynamics associated with arrhythmias showing to be useful for the prediction of the evolution towards acute states of the dynamics |

Para cada holter se analizaron los atractores generados con los datos durante 18 horas y durante toda la dinámica. Se calculó la dimensión fractal del atractor y su ocupación espacial. A estas medidas se aplicó la evaluación matemática diagnostica desarrollada previamente, comparando la evaluación para 18 horas y para todo el registro; finalmente se calculó la sensibilidad, especificidad y coeficiente Kappa.Resultados: Para las dinámicas normales los espacios de ocupación en la rejilla Kp estuvieron entre 200 y 381 en la evaluación de la totalidad del holter, y entre 201 y 384 en la evaluación durante 18 horas, mostrando la cercanía en las medidas, lo que permite que la disminución en el tiempo de la evaluación sea consistente, esta misma cercanía se observó para las dinámicas enfermas y agudas.Conclusión: Se evidenció la aplicabilidad clínica en 18 horas de la ley exponencial en la dinámica cardiaca caótica asociada a arritmias mostrando ser de utilidad para la predicción de la evolución hacia estados agudos de la dinámica.
