ECG circuit design - few questions

Well my first question is kinda broad, but, could I build this circuit exactly as is and receive an acceptable signal?
Also, Im not quite sure how the shield/shield driver work. Would the shield need to be connected to the output of the OPA336?
Also, I was initially planning on using RC LPF/HPF cascaded (Before I came across this schematic on the datasheet), but I assume there would be an advantage to sticking with the active filter?
