RECORD AN ECG
Page | 56
Acquire ECGs
Examine the display for artifact or baseline drift. Re-prep and replace electrodes if necessary to obtain satisfactory
waveforms. (See
Patient Preparation
.)
Please refer to the following troubleshooting guide based on Einthoven’s Triangle:
Artifact
Check Electrode
Lead II and III artifact
Poor LL electrode or left leg tremor
Lead I and II artifact
Poor RA electrode or right arm tremor
Lead I and III artifact
Poor LA electrode or left arm tremor
V Leads
Re-prep site & replace electrode
If a lead fault occurs, square waves appear on the display for that lead and the lead(s) that are faulty will display in
the upper left corner of the screen one at a time. After the leads are reattached correctly at least 10 seconds must be
acquired before an ECG can be captured.
The program monitors the ECG waveform for unusual configurations that could be caused by misplaced (swapped)
electrode positions. If the program detects a high probability of electrode swap, it will display a message like "RA or
LA misplaced?" in the same message area as used for lead fault. Check the electrode connections for any
misplacement.
NOTE: Although the majority of lead wire swaps are correctly detected, some real ECG configurations
may give rise to an inappropriate "misplaced" message, and some real swaps may not be detected due to
patient specific ECG morphologies. The automatic detection helps to prevent lead wire swaps but do not
rely completely on the automatic detection.
Manual ECG Capture
Use the Capture ECG
icon to capture the last 10 seconds of the real time ECG. The captured ECG will
appear on the screen in a format similar to a printout. An average beat can also be viewed if enabled.
The print ECG icon
can be used to print the unconfirmed report; if set in the configuration, the ECG will
print automatically.
ECG acquisition can also be captured by pressing the ECG button
on the WAM or AM12 acquisition
module.
Best 10 Seconds Selection
When the BEST 10
icon is selected, RScribe automatically selects the best quality10 seconds of acquired
ECG available from within the full disclosure ECG buffer.
ECG acquisition can also be captured by pressing the ECG button
on the WAM or AM12 acquisition module
when Best 10 capture has been set up. However, this action will always capture the last 10-seconds of acquired
ECG.
