Siting and Fixing the Electrodes (continued)
Fig. 4 on this page shows the conventional positions of electrodes for
recording ECG. You will notice that the patient’s RIGHT LEG is the
0 volt reference.
Essentially an ECG can be recorded from any part of the body, but
unless the conventional positions are used, the interpretation of the
results would be difficult. For more guidance, please refer to one of
the many books published which cover the recording of ECG wave-
forms.
