CMRR Test Principle and Method
When using an electrocardiograph, the 50/60 Hz noise on the ECG is often increased due to the interference of the mains signal on the human body, which may cause the doctor to incorrectly interpret the heart disease represented by the ECG waveform.

MECG 2.0 Range
The MECG 2.0 is designed around the high accuracy and test signals used in IEC 60601-2-25, with 14-bit simulation down to 2.5uV/LSB over a range of ±5mV and up to 8 channels at 1kHz, with an overall accuracy of ±5µV.

ECG Filter
ECG filters can have a substantial effect on the test results in IEC 60601-2-25, IEC 60601-2-27 and IEC 60601-2-47. In some clauses the standard indicates which filter(s) to use, but in most cases, the filter setting is not specified.

ECG Lead
From a test engineer's point of view, it is easy to get confused with LEADS and LEAD ELECTRODES, because for a typical electrical engineer, "lead" and "electrode" are basically the same thing. But there is more confusion here than just terminology.
