Resumen
This project focuses on the design and development of an electrocardiograph (ECG) utilizing
a heart rate sensor and an Arduino microcontroller, this is accompanied by an intuitive and
interactive Graphical User Interface (GUI). It fulfils the need for reliable and accessible al
ternatives for cardiac monitoring in domestic and medical contexts. The ECG is an essential
diagnostic tool that provides valuable information regarding the electrical activity of the heart,
allowing healthcare professionals to identify cardiac anomalies effectively. However, it is not
only used for cardiac disease prognoses, like palpitations or chest pain, it is also used to evaluate
symptoms like shortness of breath and dizziness, that might indicate underlying conditions like
arrhythmia.
The main goal of this project is to create a portable and inexpensive ECG device for domes
tic use as a personal health monitoring tool and for educational purposes in biomedical degrees.
The ECGsystem, based on the AD8232 sensor, includes a GUI designed to provide an intuitive
and effective cardiac monitoring experience to users. By offering a versatile and cost-effective
alternative, this project aims to enlarge access to cardiac monitoring, contributing to the cardio
vascular health of the general population and also serving as an educational tool for biomedical
engineering degree students.
The development of the ECG monitoring system encompasses multiple key aspects. The
components utilized were chosen based on their compatibility and performance with the Ar
duino board. The hardware development includes the design of a Printed Circuit Board (PCB)
and a 3D-printed enclosure to store the device securely. The software components include the
development of Python code to create the connection with the AD8232 sensor in order to pro
cess the captured data and the GUI which displays the ECG data in real-time. Filters are also
applied to the ECG to remove the noise from the registered data.
Multiple testing and validation of the ECG system were performed to ensure its efficacy
and reliability. The tests include measuring the ECG of a healthy person under different cir
cumstances to evaluate the device performance under multiple conditions. Furthermore, the
device¿s resistance to external interferences is also covered in order to ensure a reliable perfor
mance in different environments.
