The attached picture waveform is I measure in the Lab, It looks the ECG signal is almost covered by  the 50~60Hz noise(fig.1) and make it have difficulty to read the heart rate. Even worse if I move my hand, the signal becomes disappear. Could you advise me how to reduce this kind of noise?

 

   If my finger touch in the RLD pin , the waveform would be better but is still hard to read and disappear when I move my hand.
