ECG machines are expensive. This high cost can strain healthcare budgets, limiting access to vital cardiac diagnostic tools. It can also affect underfunded facilities in particular parts of the developing world or areas of conflict, potentially affecting patient outcomes and healthcare equity. We wanted to create a device just as reliable as these expensive ECG machines, using 3D printing and coding.

We have designed and built a portable ECG machine using affordable components. We used a raspberry pi and Arduino processors. We connected an AD8232 heart rate monitor and a SENO334 blood oximeter to the Arduino. Analog signals are processed by the Arduino and converted to digital data. The raspberry pi receives the digital signals and displays them on a screen. We fully 3D printed our housing for the ECG machine and its electronic components.

We have tested the device on ourselves, and it provides a clear trace of the heart rhythm on the screen. We have compared our output data to ECG trace data found online and it shows excellent accuracy.
