A team of researchers from Tsinghua University and Beijing Tsinghua Changgung Hospital has introduced a cutting-edge method to improve the interpretation of electrocardiogram (ECG) data.

A signal averaged ECG is a diagnostic test that averages multiple QRS complexes over a 10-minute time period, or at least 250 QRS complexes in order to see minute changes in the electrical ...

The differential signal then goes through a low-pass filter to remove high-frequency noise, after which it enters an ADS1291 ECG analog front-end chip. The ADS1291 contains a delta-sigma analog-to ...
