ABSTRACT

Dynamic system theory in physiology has allowed to the development of new health and disease conceptions and mathematical applications to different pathologies, such as the cardiac dynamics. Taking 15 Holters diagnosed normal and with cardiac diseases, and defining rank of the heart rates and the number of beats it was calculated the probability of each rank in 4 prototypes making comparisons between this values and those obtained for the rest. Finally it was developed mathematical parameters which differentiate normality from disease. Seventeen ranks of heart rate or more characterize a normal heart dynamic, while ranks minus than 14 are characteristic of disease. For the intermediate values: if the difference between the two more frequent frequencies is higher than 14 is sign of disease. The sum of the two more frequents heart rates is characteristic of disease when it presents values greater to 0.319 and when the difference in the more frequent heart rates also indicates disease or if both parameters appear along with a greater probability of the number of beats outside of the normality values. A physical and mathematical characterization of the cardiac dynamics was developed, useful like diagnostic aid tool of clinic application.
