Multi-Lead Analysis
Single Lead Analysis
Changing Lead Analysis
With the LEAD ANALYSIS option, you can elect to choose single lead analysis
or multi-lead analysis for ECG analysis.
Multi-lead analysis examines ECG leads I, II, III, and V (whether they are
displayed or not) to help eliminate false alarms and improve the capability of
the system to:
•
detect beats which occur isoelectric to a single chest lead;
•
discriminate artifact that appears in one lead compared to the other
lead vectors;
•
provide a ”smart-lead fail” feature where the failed lead is identified
and, if available, another lead is provided for display;
•
continue arrhythmia processing even after a lead change.
Single lead analysis uses only the
lead displayed in the top position on the
screen to process ECG and arrhythmia information.
When monitoring an adult, single lead analysis would be beneficial when:
•
using an external, temporary pacemaker with a Zoll interface cable;
•
troubleshooting pacemaker detection and/or arrhythmia detection.
NOTE: ECG is relearned whenever lead analysis is changed.
To change the lead analysis, follow this procedure:
1. Select LD ANALYSIS option from the Analysis Settings menu. A
popup menu opens displaying the two options.

2. Rotate the Trim Knob control to place the pointer in front of your
choice.
The change will not take effect until the Trim Knob control is pressed and
the popup menu closed.
3. Press the Trim Knob control to confirm the change and close the popup
menu.
NOTE: Because of the lead configuration used when monitoring neonates,
single-lead analysis defaults on with lead II in the top trace
position when the monitor is set up for Neonatal-ICU monitoring
mode.
