To get a clean ECG waveform from MAXREFDES101 do the following:
- Ensure there is a good electrical contact between the electrodes and the skin. You may clean the skin with alcohol wipes to remove any oil or dirt.
- Filter out the mains frequency as otherwise it distorts the ECG measurement
- You may need to invert the waveform depending on the location of the watch (Left hand or Right hand) as you could be measuring the inverted cardiac vector.
