ADS1298ECGFE-PDK: Differential Pair

Ray Vincent Aranzaso

Part Number: ADS1298ECGFE-PDK

Hi,

Good Day.

It is possible to use this ECG registering device to register a differential pair of leads with the RLD being only affected by those two?

I basically want to know if it is possible to use this device to act as a differential pair with the right leg drive (common ground) associated only to those pair.

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    Hi Vincent,

    Would you please clarify or elaborate more about the statement "register a differential pair of leads with the RLD being only affected by those two?"

    For ECG 3 primary leads, e.g. RA-LA, RA-LL and LA-LL, each of them is formed by two electrodes and each ECG signal is taken/acquired differentially, i.e. the voltage difference between the two electrodes.

    RLD is a 4th electrode that is recommended to attach to human body to bias the body to a known voltage(so that the body/ECG signal is not floating outside the measurable voltage range) and suppress the common mode noises.

    Thanks
