Hi,
I am working on designing an ECG using the AD623 Op Amp. So far I can input an ECG signal at 20mVPP into the AD 623 from a signal generator and produce a result (I know this is redundant I just wanted to see if it could actually work with low Voltages). When I connected the electrodes to my body and tried to recover a signal I couldn't see anything on the scope. So I used labview and filtered the signal using a low pass filter. I am only picking up a weird 60Hz signal and not my ECG. Any ideas and thought would be much appreciated.
Currently I am in the process of building a low pass filter to see if that will do anything but I have a hunch I am not actually picking up any ECG signal in the first place using my electrodes.
