AFE4900: How to get the ECG signal?

Hi

I am trying to receive an ECG signal using the AFE4900's FIFO.

However, it is difficult to receive ECG signals.

The ECG electrode is being tested using copper and the following signal is received.

(10000 data = 10 seconds, it is correct?)

Even if a filter is applied using this signal, the signal does not come out well.

How can I get the signal?

I would really appreciate it if you reply after checking.

Thank you.

Regards.
