5HFRUGLQJDQ$XWR(&*
To record an Auto ECG, perform the following steps.
1. If the cardiograph is not On, press . 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 on the front panel.
The light above the key flashes while the cardiograph is
acquiring the ECG. (If the light flashes in an alternating
pattern with the lights a leads off condition is indicated.
See “Correcting a Leads Off Condition” below.) When the
cardiograph begins printing the ECG, the
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.
