ADS1298 ECG Front-End Design

I need a compact, low-noise analog front end for a multi-lead ECG built around the Texas Instruments ADS1298. The goal is a fully validated schematic and PCB layout that can capture clean ECG signals, digitise them through the ADS1298, and present the data via an SPI interface for a downstream MCU...
