Arduino based 3-Lead ECG

Project Summary:

This project was part of my Medical Instrumentation course at UW – Madison. The assignment was to design a 3-lead ECG, acquire the signal using an Arduino Uno, and process the signal in LabVIEW. We implemented the Pan-Tompkins heartbeat algorithm in real time in LabVIEW. We designed our circuit in Eagle, performed PSpice analysis on the system, designed a PCB in Eagle, and built the prototype.

Intro and Background:

The purpose of this project was to utilize real world engineering skills and design a device from start to finish. All circuit design, circuit simulation, microcontroller code, LabVIEW code, and PCB design was performed by the students. The project was completed with a partner.
