SECTION 3
NOTE: The algorithm detecting electrode misplacements is based on normal physiology and ECG lead
order, and tries to identify the most likely switch; however, it is advisable to check the other electrode
positions in the same group (limb or chest).
 WAM Low Battery – displays when a low battery signal for the WAM is detected.
 Searching for WAM – displays when the WAM is not detected. Occurs usually when the WAM is out of
range or not powered on.
When the problem is corrected, the device waits for 10 seconds of good data before analyzing the ECG. Please refer
to the following troubleshooting guide based on Einthoven’s Triangle:
Press the ECG key. The real-time ECG view is then replaced with the acquired ECG view. The default real-time
ECG view is not available in the acquired ECG view for navigation purposes.
NOTE: New LCD label functions are available in the acquired ECG view.
NOTE: Functions are not available during acquisition.
NOTE: Change real-time display leads by selecting F2 (Leads).
To acquire an emergency (STAT) or unidentified ECG for a new patient, press the ECG key two times. “Collecting
10 seconds of data” is displayed on the top of the LCD and “captured, analyzed, formatted” is displayed on the
bottom of the LCD. To save the captured ECG, select F1 (ID) to enter patient demographics. At the “New
Patient?” prompt, select “No”. The device will display the last patient record entered. (If “Yes”, is selected the
ECG will not be saved and the user will return to the real-time ECG view.) Use the existing information, enter new
demographics, or search the directory. Once completed, select F6 (Done). Select F3 (Print) to print or
F6 (Done) to exit. Choose to save or delete the ECG at the “Save ECG?” prompt.
Best 10 Seconds Selection
The ELI 150c/250c incorporates a 5 minute memory buffer for collection of ECG data. When the Best 10 feature is
enabled, the device will automatically select the best 10 seconds of ECG from within the 5-minute buffer. The best
10 seconds is determined based upon measures of high and low-frequency noise found in the 10-second ECG
segments. Should a single limb lead or two precordial lead fail conditions occur, the Best 10 feature is disabled until
the limb lead fail or precordial lead fail condition is resolved. At resolution, the Best 10 feature becomes available
and the selection buffer continues.
Users can switch between BEST 10 or LAST 10 by selecting F5 (More) followed by F5 (Last) or F5 (Best)
depending on the current view.
