Aplicación de una metodología diagnóstica de los sistemas cardiacos en pacientes hipertensos fundamentada en las proporciones de la entropía

Resumen

Introduction: Dynamical systems theory, probability and entropy were the substrate for the development of a diagnostic and predictive methodology of adult cardiac dynamics. Objective: to apply the previously developed methodology based on dynamic systems, probability and entropy in hypertensive patients. Materials and Methods: There were selected 50 electrocardiographic records of patients with arterial hypertension with and without cardiac pathologies, 10 without known cardiac dysfunction. Numerical attractors of the cardiac dynamics were generated, and the probability of occurrence of ordered pairs of consecutive heart rates was determined. The calculation of the entropy and its proportions was carried out, and finally the statistical analysis was performed. Results: The cardiac dynamics of hypertensive patients were evaluated with the methodology based on the proportions of entropy, evidencing distinctions between hypertensive patients without concomitant cardiac pathologies and those with some type of pathology. Maximum levels of sensitivity, specificity and diagnostic concordance were evidenced. Conclusion: Proportional entropy is a diagnostic and predictive method of cardiac systems, which could be useful as a tool for objectively diagnosing and monitoring hypertensive patient
