FIXED-RATE PACING
WARNING: During fixed-rate pacing, heart rate and heart rate alarms are suppressed. Therefore, the operator shall check
for the patient’s pulse rate, not the heart rate.
PRECAUTION: The pacer pulses are delivered via the adhesive defibrillation electrodes. Separate electrodes can be
applied for acquisition of the ECG signal. Without ECG electrodes the ECG cannot be displayed.
In fixed-rate mode, the device delivers pacing pulses at the selected rate and current. The selected rate remains constant
and is not affected by intrinsic actions of the patient's heart. This is the preferred mode for cases of cardiac arrest.
NOTE: The default pacer rate can be configured. End the therapy as described under "Demand Pacing” above.
1. Check that the ECG electrodes and the pace pads are correctly applied and connected to the device.
2. Use the Rotary Selector Knob to turn on the pacemaker. The device defaults to the Demand Mode, if separate
electrodes are applied and selects a pacer rate of 60 PPM (configurable).
3. Turn the Focus to the Demand field to activate the fixed-rate pacing mode by selecting Fix Mode, using the Rotary
Selector Knob.
4. Select the required pacer rate.
5. Now increase the pacer current output slowly until the heart reliably responds to the stimulation.
6. Increase the pacer current output another 5 mA to ensure continued stimulation.
