Updated Nov 30, 2011 by Thai.Ngu...@gmail.com

Introduction

This page discusses the hardware design used for the Arduino-based ECG. The design is based on an article by Darko Petrovic called Analog Front-End for a Simple Electrocardiogram.

Details

Materials

The materials used for the Arduino-based ECG and the estimated costs are listed below.
