Problem with the ECG amplifier

[wavestorm1986]

hi everybody. 

i am working on an ECG project, so as a first stage i must design the ECG sensor, my project will need also labVIEW later on, so i download  the ECG virtual signal which can be found by pressing on the labVIEW icon inside MULTISIM but what ever i try any circuit i didnt find the solution for the output. plzzz i need help any advice will be thankful.

 i will post down what i did so far, by the way the ECG generator have to change the common mode=4.8 and the frequency=8 

then  if you chose the oscilloscope next to the ECG signal, can see the pure signal BUT at the last oscilloscope there are nothing. i used many types of op-amp but nothing can work.

wavestorm1986,

Here is a working circuit showing the ECG example.   You may have to substitute in the circuit with the ECG instrument you have downloaded.

hi Patrick Noonan

thanx for ur help, but i already test this ad i know how its work. my idea is to use anther type of instruments amplifier and coneected to the ECG signal in multisim 10 so at least at the end i will buy these things then apply it to my application.

plz if u have any idea about a circuit which already tested in mutisim plz let me know sir.

thanx in advance
