Electromagnetic Interference Possible electromagnetic interference
The device is protected from electromagnetic interference and electrostatic discharges. Also, the emitted interference has been reduced to a minimum. Thus the device conforms to the requirements of EN 606011-2 (in its current version at the time of delivery). However, strong electromagnetic interferences that occur in the close vicinity of electrical motors, power cables, PCs, monitors, or other – possibly defective – electrical devices may compromise the function of the device in certain cases. This kind of device malfunction should be considered as a possible cause if the following is observed: The device detects intrinsic cardiac events that cannot be seen in the ECG. The device displays other inexplicable functions. In the case of disruptions resulting from electromagnetic interference (EMI) that exceed certain limits, the Qubic Stim switches to the Fixed pacing mode. Pacing is performed with the set pacing rate. Correct operation of the device can be restored by the following methods: Switch off the malfunctioning electronic device. Remove the source of interference from the device. Switch the device on and off or break the electrical connection between the device and the source of the interference if this can be done safely. If the interference continues, contact BIOTRONIK immediately. Note: If accessories other than those specified by BIOTRONIK are used, increased interference or lower resistance to interference can be expected. Note: If accessories specified by BIOTRONIK are used on other devices, increased interference or lower resistance to interference can be expected. Note: Radio communication devices can interfere with how the device functions.

Electrostatic potentials
Ensure that electrostatic potentials between medical staff and patients are balanced. Before handling the device, the electrostatic potential between the physician or medical staff and the patient must be balanced by touching the patient at a point as far away from the catheters or leads as possible.
Leakage currents
Avoid leakage currents between all connected devices. Such leakage currents can cause lethal arrhythmias. Potential equalization cables must be attached to all connected components, if present. Before initial commissioning, check and document all device combinations. National and international directives concerning the use of electromedical devices also apply to patient cables.
Sensitivity
A higher sensitivity level as set by selecting a lower sensitivity value will lead to more frequent interference from electromagnetic fields. Low sensitivity values should only be set if absolutely necessary for medical reasons.
Touching contacts on cables and catheters
Do not touch the contacts on the patient cable or on the catheter. The device has electrical contact with the patient's heart and blood via the implanted catheters. Touching the contacts on the patient cable or catheter could expose the patient's heart to dangerous electrical currents.
Defibrillation
When connected with the approved patient cable, the device is defibrillation protected. However, damage cannot be ruled out in all circumstances. Check all functions of the device, following a defibrillation. During defibrillation, do not touch the patient, the device the patient is connected to, or the attached accessories. Otherwise, there is a danger that you may suffer an electrical shock.
Risk of infection
Contaminated devices can lead to infection. Clean and disinfect the device on a regular basis. Observe the cleaning instructions for all other system components.
