A portable ecg monitor based on arduino-uno with ad8232 board in monitoring the cardiac physiological system

The electrocardiogram (ECG) is a record of electrical phenomena that originate during cardiac activity to the cycles of polarization and depolarization of cardiac cells pass around the heart itself and a small part of these waves of electrical tension can travel up to the body surface by capturing the signal from the electrodes on top of the skin. However, the high cost and the inaccessibility of the ECG limit the use in scientific research or hospital center in a region with little investment in medical and hospital equipment. The aim of present study was to build an ECG prototype that monitors the electrical activity signal of the heart based on the cardiac sensor AD8232 designed to extract, amplify and filter the biopotential ECG signal with three electrodes, in which it is coupled essential to operate on Arduino with the objective of digitizing the analog signal by the microprocessor from the lines of codes configured in a script enabling its use through a USB connection. Finally, to be designed in the software visualization of the ECG signals. The results obtained, using the script, showed that it is possible to perform the monitoring of electrical activity with the identification of the P wave, the QRS complex and the T wave. In conclusion, the Arduino with AD8232 board for cardiac monitoring of simple and inexpensive technology that makes it possible to develop scientific research in the field of cardiovascular health and the examination of cardiac monitoring in complete communities that have difficulty in accessing the professional ECG.
