ecg circuit

Hello! I am trying to simulate an ECG Front End Configuration which is shown in the figure below. What should be my equivalent circuit for the human person? I am only using Electronics Workbench. Thanks!

 

equivalent circuit of the human body

download ecg signals in .wav format and then apply to it.
 

ecg front end circuit

i think its going to take so much time to extract signal from the wav files.. i think i can just use a signal generator or a sinusoidal ac source for that. My main concern is to what I should connect with the right leg drive

Thanks! If I understood the journal right, it focused on an rc model for a high frequency signal. In the introduction, it only mentions the conventional low frequency equivalent model of the human body. Standard ECG application has only 0.05 Hz to 100 Hz bandwidth so I guess this belongs to low frequency signals and thus I should follow the conventional circuit model which assumes zero resistivity and some capacitor values ( I have to read references 1 and 2 for proper values of the capacitor ).

Another question, ECG signals are usually 0.5mV to 5mV ( others say 0.2mV to 2mV). Is it ok to implement this using breadboard?

Thanks
