Precordial Lead ECG Monitoring
The precordial (chest) leads (see Table, ECG Leads Color Codes (on page 54)) can be used
for monitoring when using the 12-lead cable or 5-wire cable.
To perform precordial lead ECG monitoring:
1. Insert the precordial lead attachment into the main cable as shown in Figure, 12-Lead, 3-
Lead, 4-Wire, and 5-Wire ECG Cables (on page 52).
2. Place the precordial lead electrodes on the chest as described in the 12-lead ECG
procedure and shown in Figure, Precordial Lead Electrode Placement (on page 60).
Note:
When using a 5-wire cable, attach the limb leads as described in ECG Monitoring
Procedure (on page 53), and place the C-lead electrode on the chest in the precordial
position desired. Note that the LIFEPAK 15 monitor labels the ECG for this lead as V1 on the
screen and printout, regardless of the location of the C-lead electrode.
Leads Off
If an electrode or lead wire disconnects during ECG monitoring, the monitor emits an audible
alarm and displays a
LEADS OFF
message. The ECG trace becomes a dashed line. The alarm
and messages continue until one of the following actions is performed:
• The lead wire is reconnected
•
The lead selection is changed to a lead using connected lead wires
• Power is cycled.
Color Coding for ECG Leads
The lead wires and the electrode snaps for the patient ECG cable are color coded according
to American Heart Association (AHA) or International Electrotechnical Commission (IEC)
standards as listed in the following table.
