Keywords:common-mode rejection? electrocardiogram? ECG?

Here's a discussion on the need to improve common-mode rejection (CMR) in electrocardiogram (ECG) subsystem applications. Several different techniques to improve CMR while also considering both patient and operator safety are presented. This report also reviews the implementation of the right-leg drive (RLD) loop technique to improve CMR using the ADS129x family of analog-to-digital converters (including the ADS1298/96/94 and the ADS1198/96/94) and the corresponding performance results.
