CAUTION
Damage to the seal
Ensure that the sealing rings of the lead connectors are not damaged by the
alligator clips.
This applies especially when connecting an alligator clip to the exposed contacts.
!
!
WARNING
Leakage currents can trigger ventricular fibrillation
Only conduct electrophysiological measurements or temporary pacing through
implanted leads with devices that are classified as type CF (Cardiac Floating)
applied parts complying with EN 60601 or with battery-powered measuring and
pacing devices.
All other line-powered devices connected to the patient must be properly
grounded.
!
!
CAUTION
Risk of intermittent pacing
During intracardiac measurements, pacing will be temporarily interrupted.
Connecting the leads
temporarily
For a qualitative evaluation of the lead position, it is necessary to measure pacing
thresholds, intracardiac potentials and the defibrillation threshold.
For this purpose, temporarily connect the patient cable to the lead connectors using
alligator clips. The pin of the IS-1 connector can be accessed via an opening in the
stylet guide.
The contact ring of the IS-1 connector is directly accessible for alligator clips.
DF-1 connectors can only be connected using a suitable adapter.
The DFT test requires an antipole, such as a test housing.
Clamping an alligator clip to the connector pin:
Use suitable patient cables when temporarily connecting the lead to an
intraoperative test system. The stylet must be removed prior to the measurements.

Please note the following when conducting intraoperative measurements and tests!
