AD8232 low frequency drifting

We are using circuit similar to the reference design, can get good result with some electrodes. However, when using some other electrodes brand, the signal has lots of low frequency drift: lower than 0.4Hz, and amplitude is like rail to rail, the real signal rides with it. The drift part of signal changes all the time.


Could you please help? Some other instrument has no problem to all the electrode pads.
