Adjusting the ECG and EGM Traces
The control buttons at the left of the trace display (see below) let you adjust
the displayed ECG and EGM.
To make an adjustment:
1. Select the appropriate button (see descriptions below).
2. Select the desired option from the displayed window of options.
Select to choose a different ECG Lead configuration.
Options: Lead I, Lead II, Lead III (Lead II is the default setting.)
____________________________
Select to change the ECG amplitude scaling.
Options: 1.0, 0.5, 0.2, 0.1, 0.05 mV/mm and Automatic.
“Automatic” sets scaling to the highest value that does not result in clipping
of the waveform peaks. Automatic is the default setting.
____________________________
Select to turn the ECG filter ON or OFF.
Options: Filter OFF (Bandwidth = 0.05 to 100 Hz)
Filter ON (Bandwidth = 0.5 to 40 Hz)
The ON setting may improve clarity of the displayed and printed ECG in
the presence of interference. “ON” is the default setting.
____________________________
Indicates the patient’s present heart rate. This is not a control. The dis-
played value is a beat-by-beat measurement derived from Marker Channel
telemetry. For ventricular and dual chamber modes, the value will be the
ventricular rate; for atrial modes, the value will be the atrial rate.
_______________________________
Select to display programmable waveform telemetry options.
(See telemetry programming procedure next page).
____________________________
Select to change the EGM amplitude scaling.
Options for: A. EGM = 1.0, 0.5, 0.2, 0.1, 0.05 mV/mm and Automatic
V. EGM = 5.0, 2.0, 1.0, 0.5, 0.2 mV/mm and Automatic
“Automatic” sets scaling to the highest value that does not result in clipping
of the waveform peaks. Automatic is the default setting.
