b. Apply the new electrodes on V3R and V7 sites.
c. Remove the V3 lead and attach it to the V3R electrode.
d. Remove the V4 lead and attach it to the V7 electrode.
Refer to “Patient Preparation” of this operation manual for additional information.
3. Select the ECG test after entering the relevant information.
4. Adjust the sweep speed and gain as necessary:
• If artifacts or noise occur in the ECG signal, please refer to ECG signal quality problems in the Troubleshooting Guide
for corrective actions. Do NOT turn the muscle filter on for pacemaker patients.
5. Wait for the ECG tracings to pass the screen twice (about 20 seconds) to verify that the signal quality is good and the baselines
are stable.
6. To acquire a test report, click Acquire on the ECG tab, or click Start on the Rhythm tab as follows:
• Acquire instructs the program to acquire, analyze, and store a resting ECG test.
• Start instructs the program to begin acquiring a preset duration of the rhythm strip, and prepare a Rhythm report.
7. Reports can be automatically viewed after acquisition, and can be saved or redone from the review screen.
Appendix C – Upgrading IQmanager
®
software version 8.5 and earlier
The following describes the changes to the original QTc data in the ECG reports with previous versions of IQmanager
®
software after
this upgrade:
• Information on the old ECG reports will remain the same as long as no changes are made to the report.
• The original QTc information will no longer be editable. This value will be fixed.
• Add up to two of the four available QTc data to include in the ECG report. See “ECG Configuration Setting”.
• Changes made to the ECG report that have the original QTc information may remove it from the report. The general rules
of thumb are as follows:
1. Changing the interpretation statement or general measurement values, other than heart rate or QT, will retain the
original QTc data. This is to preserve the original QTc value to support the physician’s interpretation. Additional QTc
information will be added to the report based on the current selections in QTc 1 and QTc 2 settings.
2. Changing the heart rate or QT value will remove the original QTc data and replace it with the current selection in QTc 1
and QTc 2 settings. The original QTc value is redundant in this case since QTc will be recalculated based on the new
heart rate or QT values.
3. If the report already has the QTc 1 and/or QTc 2 data, any changes to the report will update the QTc 1 and QTc 2
information based on the current selection in these settings.
• A warning message will appear to inform the user of the changes in QTc data when you begin to edit the report. Accept
the change in order to edit the report.
• Optional: Check “Do not show any New QTc Formula Update message again” to disable the warning message.
• The original QTc data in the Measurement Matrix will be removed and replaced by the new QTc 1 and QTc 2 information.
• Accessing the P-QRS-T Calipers will display the QTc information based on the current QTc 1 and QTc 2 settings. Moving the
calipers that measure the QT interval will automatically update the new QTc values according to the specific formula.
• Similar to the original QTc information, the system does not allow the user to change the new QTc data directly. However,
changing the heart rate or QT value will automatically update the new QTc data according to the specific formula.
