Prototipo Ecg con Transmisión de Información a Dispositivos Android

Abstract

This article describes the development of the graduation project for title of electronic technologist, based on a prototype ecg portable three derivations that transmits information to Android for their respective display devices, the application features expand, stop, spindle lock and one of the most important features that differentiates it from similar works is the ability to save a .txt file named with the date on which the analysis was conducted , this file is housed in the external memory (microsd) team by default do not possess is saved in the root directory of the phone in a folder called ECG. The .txt file is stored the vector of values that make up the graph, this information can be sent to a remote user via email or bluetooth, this file can be opened again with the application with the button read and select the file to visualizar.EL prototype of acquisition is of small size and only very low-power 3.3V by what is powered by a battery of cell that it can be charged at the time that runs out with a mini USB cable. Consists of a module ecg AD8232 that is already designed to capture the signal from the heart with great quality through 3 disposable electrodes, which are connected by a 3.0 Jack to the module, an arduino nano which performs analog conversion digital and module Bluetooth hc-05 to transmit information to the android device. Then we outlined the objectives set out in the project: GENERAL OBJECTIVE • Develop a prototype ECG (electrocardiograph) and make use of ICT (information technology and communications) to he sent information to a remote user. SPECIFIC OBJECTIVES • Get the parameters of the ECG (curve PQRST) within established standards to be able to use this information in a possible medical diagnosis. • Establish a proper communication channel to send data from the ECG to a remote user for analysis. • Diseño de una Aplicación para dispositivos Android (App) como medio de visualización. • Design of an application for Android (App) as a means of display devices.
