Monitoring the ECG
For general troubleshooting tips, see Table 10-2 on page 10-18.
ECG amplitude too small Poor electrode-skin contact • Prepare skin and apply new
electrodes.
ECG lead selected • Increase ECG gain or change ECG
lead.
Patient condition (for example,
significant myocardial muscle
loss or tamponade)
• Increase ECG gain or change ECG
lead.
Monitor displays dashed
lines with no ECG

messages
PADDLES lead selected but
patient connected to ECG
cable
• Select one of the limb or
precordial leads.
Monitor shows isoelectric
(flat) line and
PADDLES lead
selected
The Test Load is connected to
therapy cable
• Remove the Test Load and
connect therapy electrodes to
cable.
• Connect ECG cable and select
another lead.
Internal pacemaker pulses
difficult to see
Pacemaker pulses are very
small
• Turn on internal pacemaker
detector (see "Monitoring Patients
Who Have Internal Pacemakers"
on page 4-11).
Monitor frequency response
limits visibility
• Connect ECG cable and select a
lead other than
PADDLES.
• Print ECG in Diagnostic mode
(see "How to Print a Current
Report" on page 7-10).
