Design of a Three Electrodes , Three Leads ECG System

Abstract

The overall objective of this project is to provide a new ECG system Design based on a modified single channel ECG system with multiplexer circuit to record and display the three ECG leads (I, II and III ) simultaneously by three Electrodes to reduce complexity associated with traditional multi-channel ECG system. The suggested system record the three leads by switching the three electrodes on single instrumentation amplifier , in Each stage two electrodes are active and the remaining electrode act is the reference .
