we have problems to get good Stress ECG signal with ADS1198/1298. Diagnostic ECG signal records are fine, but ECG in stress has excesive fast baseline wander. Does anyone know what do we have to do to get good stress ECG signal records?

Thanks Brian!
we have been trying different digital algorithms alternatives but it seems like the ADS has some problem with baseline wander because normally this kind of fluctuations dont get into the ECG bandwidth. Probably, we are omitting an analog circuitry prior of the ADS. Is there any recommendation?
Thanks Brian!
We´ve been working with INA122 for some years and we have implemented a lot of those digital algorithms with very good results (we have published some of them, also), but it seems like the ADS1298 does not work well with stress ECG, unless there is something else that we dont know or find in your white papers...
Do you know if is there any application datasheet for stress ECG?
I attach below our work paper schematic of a part of the device that uses ADS1298 and the instrumentation made with INA122 that has no problems whith stress ECG. As you can see there, we work with active Right Leg in the ADS1298 design, whereas in the INA122 design we have passive Right Leg. The electrodes are the same (3M).
Any help will be wellcome!
