Projeto de um eletrocardiógrafo emergencial para pacientes com COVID-19

Abstract

An enormous international effort was made in response to the public health crisis caused by COVID-19, which began in the Chinese city of Wuhan in December 2019. This effort was especially focused on the development of ICU devices, such as oximeters and electrocardiographers for monitoring patients' cardiac electrical activity. To enable their mass manufacture and low cost, it was necessary to simplify these expensive devices while maintaining the barest minimum of capability. Since it is now recognized that COVID-19 not only causes lung problems but also cardiac and brain problems, such as acute myocardial infarction and stroke, this endeavor aims to build an emergency use electrocardiographer for emergency ICUs and the subsequent monitoring of these patients. The newly created electrocardiograph just has a D2 channel and does not need a computer to monitor and record cardiac electrical activity because it is displayed on an Android-powered smartphone's screen. The Arduino, a microcontroller-based plate, is used to record, analogically filter, and digitize the electrocardiographic signal. A mobile phone running the Android operating system receives this signal through a Bluetooth serial module and displays it on the screen. The created device requires a 9V battery, three standard electrodes, disposables for electrocardiograms, and pressure to secure the electrodes to the patient's body. Using this knowledge, medical personnel can quickly identify the patient's heart issues by checking their mobile device.
