Diseño de un sistema de análisis de anomalías en señales electrocardiográficas usando WFDB TOOLBOX de MATLAB.

Abstract

The present degree work aims to explain the development of a system for recognizing anomalies present in electrocardiographic signals, since these anomalies are what allow the cardiologist to make an assessment of whether the patient's heart is working correctly or on the contrary. have some type of heart disease or heart disease. To carry out this project, the MATLAB® software was used, more specifically its WFDB tool, which allows us to access the PhysioNet databases, from which the physiological signals used during the development of this project were obtained. Once the databases with the electrocardiographic signals to be used had been obtained, we proceeded to determine which aspects of them are sufficiently relevant or have valuable information on the state of functioning of the heart, where it was found that the duration of the RR intervals, PR, QT and ST, in addition to the cardiac cycle being complete and normal, that is, the waves that compose it are complete and in the correct order, and finally that the durations of the separate waves do not exceed normal limits . These are the most important aspects of the electrocardiographic signals and from which the cardiologist makes the opinion or diagnosis of the patient.
