Monitoring the ECG
Precordial Lead ECG Monitoring
The precordial (chest) leads (see Table 4-1, "ECG Leads Color Codes") 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 4-2 on
page 4-8.
2. Place the precordial lead electrodes on the chest as described in the 12-lead ECG procedure
and shown in Figure 4-5 on page 4-16.
Note: When using a 5-wire cable, attach the limb leads as described in "ECG Monitoring
Procedure" on page 4-8, 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 the electrode or lead wire is replaced.
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 Table 4-1.
