Construcción de un sistema Electrocardiográfico con conexión inalámbrica a teléfonos inteligentes

Abstract

According to the World Health Organization, cardiovascular diseases are the leading cause of death worldwide. For prevention, diagnosis and treatment of heart disease, a medical examination known as electrocardiogram is required, the exam records the electrical activity of the heart and is acquired through a device called an electrocardiograph. In the same way, there is a growing motivation towards the development of new technologies to monitor health and ensure the general well-being of the population, which is speeded up through the rise and advancement of mobile devices. This paper presents the design and implementation of an electrocardiograph which allows the graphic display of the electrocardiographic signal on a mobile device with Android operating system and has an interface to a personal computer where the signals obtained are deployed, processed and analyzed. To build the device, an evolutionary-incremental methodology was followed. The functioning of the system was evaluated in the detection of arrhythmias and acute myocardial infarction; achieving performance indicators of TPR = 87.50% for signals with arrhythmias and TPR = 92.59% for signals with infarction. In this way, information can be captured, processed, parameterized, transmitted, stored in integral health computer systems and used to perform diagnostics by remote specialists; profiling, this system, as alternatives for the diagnosis, care and monitoring of people who have heart problems.
