Hi,
Right now, I am designing a hardware circuit to read the ECG signal where the output signal will eventually be read by n oscilloscope. I have already build the circuit, using AD620 as the IA and OP177 GPZ as my op-amp. I am referencing my circuit from this website :

Right now when I connect the output of the whole circuit to the oscilloscope, this is what I get.

Also, I took a picture of the signal output where it is just after the AD620 output. If you look at this picture, there is certainly an ECG signal but with a little noise. May I know what is wrong ?

I would appreciate the help that I can get from you guys.
