Desenvolvimento de um sistema holter de eletrocardiograma

Abstract

The objective of the present study is to present a holter electrocardiogram (ECG) system, built from low cost devices, based on proposals already on the market as a basis for the elaboration of the same. This type of system is used to collect long periods of the electrical activity of the heart in order to look for moments that could not be analyzed in a common examination, which takes about a few minutes. Devices that could be used for the application as well as development platforms for the job were listed. The signal used for the application was removed from the MIT-BIH using a microcontroller and a digital-to-analog converter (DAC) as a simulator. The software was developed through the IDE Arduino, by affinity. The results are stored in files, which will be read with Virtual Instruction (VI) developed for the application, based on LabView. The device is powered by 3.7V lithium batteries, associated in series, as it is a portable device. The signals collected by the Holter device, represented with fidelity the signal generated by the simulator developed for the application, represented in the VI.
