How can we implement 3 electrode (only 3) and 6 channel ECG with only one ADS1293 ?

How can we implement 3 electrode (only 3) and 6 channel ECG with only one ADS1293 ?

We can calculate goldberger , but how can we eliminate rld ?

What is the effect of coupling vdd/2 to each electrode with a 10Mohm or high valued resistor , instead of using rld?

What is the effect of coupling RLD to each electrode with a 10Mohm or higher resistor ?

    MehmetCan,

    ADS1293 is a TI product and is not supported through this forum.  If you would like assistance with an ADI ECG offering such as ADAS1000 please resubmit your question with reference to that product.   To aid in answering your question please submit any relevant schematics/drawings that might provide insight to your specific design challenge.
