Design of a low-cost portable electrocardiograph for telemedicine application

This paper presents the design of a portable electrocardiograph designed to provide community health care. The AD8232 main sensor has multiple options for displaying cardiac activity. The first option uses the serial plotter in the Arduino IDE, while the second employs LabVIEW, allowing additional observation of the patient's blood pressure via block coding. In addition, the Arduino cloud is integrated to process the information captured by the ESP32, enabling visualization on any device with internet access. Through this platform, it is possible to download the studies performed in different periods (1 hour, 1 day, 7 days, and 15 days), with an efficiency percentage of 4.11%.
