Recording an Auto
ECG
Correcting a Leads
Off Condition
To record an Auto ECG, perform the following steps.
1. If the cardiograph is not On, press (WlL). The
front panel lights are lit as the cardiograph performs a
short power-on sequence.
2. Prepare the patient and apply the electrodes.
3. Press (Auta) on the front panel.
The light above the (Auto) key flashes while the
cardiograph is acquiring the ECG. (If the IAuto)
light flashes in an alternating pattern with the
(Manual) lights a leads off condition is indicated. See
"Correcting a Leads Off Condition" below.) When
the cardiograph begins printing the ECG, the (Auto)
light stays on. When the cardiograph has completed
the report, the light turns off.
A leads off condition is caused by the patient cable
not being connected to the cardiograph, one or more
leadwires not being connected to electrodes, or poor
contact between the patient and one or more electrodes.
The cardiograph signals a leads off condition only
during the acquisition of an Auto ECG. The operator
can check for a leads off condition anytime an ECG
report is printed by checking for traces consisting of
dashed lines or by checking the upper left corner of the
Auto ECG report for a leads off message. The leads off
message lists the lead wires or electrodes that have a
leads off condition. Table
2-1
shows the possible leads off
messages, and the lead wire and electrode to check for
each one. To correct a leads off condition, perform the
following steps.
1. Check that the patient cable is properly connected.
2. Recheck the steps you performed when preparing
the patient. Pay particular attention to the proper
application of the electrodes and the connections
between leadwires and electrodes.
