Recording an ECG

• Red indicates a lead-fail condition or extreme baseline shifts. The red indicator is

always the left-most circle of the of the indicator and flashes when lit.

• Yellow indicates muscle artifact, power line interference, baseline wander, or

electrode noise. The yellow indicator is always the middle circle of the of the
indicator.

• Green indicates generally acceptable signal quality. The green indicator is always

the right-most circle of the of the indicator.

When the lead quality is red or yellow, a message describing the lead problem or
status is displayed on the screen.

Hookup Advisor is enabled and configured in the ECG Acquisition menu (

System Setup

>

ECG

>

ECG Acquisition

). Refer to

“ECG Acquisition” on page 124

for more information.

In addition to enabling/disabling the Hookup Advisor feature, you can set the level at
which the system acknowledges poor signal quality. The acknowledgement level can
be set to Yellow, Red (default), or Never.

Hookup Advisor continuously reviews the ECG data for acceptable lead quality.

• If

Pre-acquisition

is enabled in the system setup, the lead quality indicator will

reflect the entire previous 10 seconds of ECG data. Any displayed messages will
be updated on a real-time basis to reflect adjustments/improvements to the lead
quality. Once any lead quality problems have been remedied, the message

Please

wait...

will be displayed until the entire 10-second period is free from lead quality

problems.

• If

Pre-acquisition

is not enabled, the Hookup Advisor level and messages will

respond to a fixed poor lead quality problem within two to three seconds.

When an ECG is acquired, Hookup Advisor runs a complete and more comprehensive
assessment of the full 10 seconds of ECG data and possibly prompts the user
regarding any poor lead quality conditions.

• If

Preview before analysis

is turned off in the system setup, a lead quality message

and prompt may be displayed, depending on the current lead quality level and the
