4: ECG Monitoring Preparing to Monitor ECG
50
Figure 40 shows the typical electrode placement for a 5-lead ECG set.
The single V/C lead may be placed in any of the precordial electrode positions as shown in Figure 41
(V1/C1 through V6/C6).
NOTES: No matter which V/C electrode placement you select, it appears as V on the Efficia DFM100.
If using a V electrode, it can act as a reference electrode if the RL electrode is unavailable.

Figure 41 V/C Electrode Placement
LL/F (red/green)
placement: on the
left lower abdomen
LA/L (black/yellow)
placement: directly
below the clavicle and
near the left shoulder
RA/R (white/red)
placement: directly
below the clavicle and
near the right shoulder
RL/N (green/black)
placement: on the right
lower abdomen
V/C (brown/white)
placement: on the chest;

V/C 1 placement: fourth intercostal space at
right sternal margin
V/C 2 placement: fourth intercostal space at
left sternal margin
V/C 3 placement: midway between V/C 2
and V/C 4
V/C 4 placement: fifth intercostal space at left
midclavicular line
V/C 5 placement: same level as V/C 4 on
anterior axillary line
V/C 6 placement: same level as V/C 4 at left
mid axillary line
