Plug connector damaged!
Impairment with electrical safety and function
→ Carry out a careful visual and functional test of the connector
Temperature or impedance set point exceeded!
Impairment with electrical safety and function
→ Bring the catheter tip to a straight position with the curvature control and then pull them out and
remove coagulation deposits from the tip (cleaning). Leave the electrode tip in a straight position when
cleaning. Avoid rotating or scrubbing to prevent damage to the connection point and the electrode tip
or the electrodes becoming loose.
More than 30 ablations conducted, each with one minute of power supply!
Hazard due to loss of function or loose tip electrode
Do not perform more than 30 ablations at a time with a power supply of over one minute or less.
No anticoagulant is administered!
Application for thromboembolism
→ Administer intravenous heparin in the left ventricle during access for ablation purposes. There is still no
consensus concerning of the need to use anticoagulants after ablation.
The medical personnel have not been adequately trained!
Fault when making intracardiac potential recordings and/or stimulation
→ A prerequisite for making an intracardiac potential recording and/or stimulation is the appropriate
training of medical staff and the availability of a fully equipped electrophysiology laboratory. The
procedure itself must only be performed by a trained and experienced physician.
Lack of care when handling the catheter!
Injuries of the heart, perforation or tamponade
Take great care when handling the catheter.
→
Dispersive electrode(s) improperly attached, incorrect electrodes or failure of electronic cables!
Low power drain, increased impedance or equipment malfunction despite correct device
settings
→ Ensure that the dispersive electrodes and their connectors are correctly attached. Check the device for
faults or incorrect attachment before you increase the power supply in the case that the power drain is
too low.
→ The dispersive electrodes used should comply with or exceed regulations according EN 60601-2-2.
Improper handling of the catheter, generator or accessories!
Injury to the patient and/or medical personnel and/or technical facilities
→ The relevant instructions for use must be read and understood before using the catheter or the
external pacemaker.
Any static electricity must be kept away from the catheter system. Special care must also be taken to
→
provide adequate and central grounding of the operating table and the electrical devices used (e.g. X-
ray machines).
Conductive paths created for ablation alternating currents via the electrodes and probes of monitoring
or stimulation instruments!
