Notes on ECG Leads
• DC means direct current
• RA means right arm
• RL means right leg
• RMS means root mean squared
• AC means alternating current
Lead Off Detection Currents Leads off detection uses a DC lead off current of 12 nA for RA
and 27 nA for the all the other electrodes except RL.
Right leg electrode depends on the number of electrodes
connected, but has a DC current of typically 71 nA rising to 83 nA
in the worst case lead configuration.
Active Right Leg Drive Current The AriaTele transmitter has an active right leg circuit. The
maximum right leg drive noise cancellation current is limited
to <4.8 uA RMS AC and <9.5 uA DC, and a maximum voltage of
1.5 V RMS AC.
