Webof the ECG signal itself. The key to extracting the desired ECG signal from the 50Hz noise is the fact that the ECG signal is the difference in potential between a pair of electrodes, ie a differential voltage. On the other hand, the 50Hz noise voltage is common to each electrode (it appears equally at both the Right Arm and Left Arm input ... Webleads and their geometry. The EKG waveform comes from a measurement of surface voltages between 2 leads. A wave that is travelling towards the positive (+) lead will inscribe an upwards deflection of the EKG; conversely a wave traveling away from the positive lead will inscribe a downward deflection.
