Operation Pacer mode setting

Three different operation modes for the Pacer are available:
- DEMAND (Default)
- FIX
- OVERDRIVE
Operation Features
Mode
The stimulation occurs only on demand, which means only if the
DEMAND
inherent heart frequency decreases under the DEMAND-
(Default)
frequency value.
FIX Fixed frequency stimulation, which means independently from
the inherent heart rate a fixed heart rate is forced.
OVERDRIVE Over stimulation of the heart with a high frequency (max. 250
1 /min) to terminate e.g. ventricular tachycardia.
After switching the device on, the operation mode DEMAND is automatically acti-
vated. The operation mode is displayed in the monitor in a text window. To switch to
another operation mode press the operation mode key once or several times until the
desired operation mode is displayed.
While setting the operation mode, stimulation impulses are not yet generated.
During pacing, the operation modes can not be switched. Before switching e.g. be-
tween FIX and DEMAND mode, the Pacer has to be stopped.
If pacing is reactivated without a change of the operation mode the previously set
stimulation parameters are applied. if the operation mode is switched, or the Pacer is
switched off and on again, the default stimulation parameters are reactivated.

Stimulation frequency setting

Depending on the operation mode of the Pacer different stimulation frequencies
(number of pacing impulses per minute) can be set:
FIX, DEMAND
OVERDRIVE
When activating the respective mode the following frequency values are pre-set:
FIX, DEMAND
OVERDRIVE
If a different stimulation frequency is indicated, the frequency can be changed by the
Pacer-Frequency + key or the Pacer-Frequency - key. The alteration occurs with each
key press in steps of 5
also be altered during pacing.
If the keys Pacer-Frequency + or - are pressed continuously, the frequency is stepped
each half second. If the key is released, the frequency remains at the last adjusted
value.
The stimulation frequency should only be adjusted if this is absolutely necessary. Al-
terations need to be done under strict ECG monitoring, since the patient, under cer-
tain circumstances, will react differently on the new stimulation parameters.
